1.1 Overview

ARM®core with embedded Flash & RAM

The STR710 series is a family of ARM-powered 32-bit Microcontrollers with embedded

Flash and RAM. It combines the high performance ARM7TDMI CPU with an extensive

range of peripheral functions and enhanced I/O capabilities. STR71xF devices have on-chip

high-speed single voltage FLASH memory and high-speed RAM. STR710R devices have

high-speed RAM but no internal Flash. The STR710 family has an embedded ARM core

and is therefore compatible with all ARM tools and software.

Extensive tools support

STMicroelectronics’ 32-bit, ARM core-based microcontrollers are supported by a complete

range of high-end and low-cost development tools to meet the needs of application

developers. This extensive line of hardware/software tools includes starter kits and complete

development packages all tailored for ST’s ARM core-based MCUs. The range of

development packages includes third-party solutions that come complete with a graphical

development environment and an in-circuit emulator/programmer featuring a JTAG

application interface. These support a range of embedded operating systems (OS), while

several royalty-free OSs are also available.

For more information, please refer to ST MCU site http://www.st.com/mcu

Package Choice: Low Pin-Count 64-pin or Feature-Rich 144-pin LQFP or BGA

The STR710 family is available in 5 main versions.

The 144-pin versions have the full set of all features including CAN, USB and External

Memory Interface (EMI).

●STR710F: 144-pin BGA or LQFP with CAN, USB and EMI

●STR710R: Flashless 144-pin BGA or LQFP with CAN, USB and EMI (no internal Flash

memory)

STR71xF Introduction

5/74

The three 64-pin versions (BGA or LQFP) do not include External Memory Interface.

●STR715F: 64-pin BGA or LQFP without CAN or USB

●STR711F: 64-pin BGA or LQFP with USB

●STR712F: 64-pin BGA or LQFP with CAN

High Speed Flash Memory (STR71xF)

The Flash program memory is organized in two banks of 32-bit wide Burst Flash memories

enabling true read-while-write (RWW) operation. Device Bank 0 is up to 256 Kbytes in size,

typically for the application program code. Bank 1 is 16K bytes, typically used for storing

data constants. Both banks are accessed by the CPU with zero wait states @ 33 MHz

Bank 0 memory endurance is 10K write/erase cycles and Bank 1 endurance is 100K

write/erase cycles. Data retention is 20 years at 85°C on both banks. The two banks can be

accessed independently in read or write. Flash memory can be accessed in two modes:

●Burst mode: 64-bit wide memory access at up to 50 MHz.

●Direct 32-bit wide memory access for deterministic operation at up to 33 MHz.

The STR7 embedded Flash memory can be programmed using In-Circuit Programming or

In-Application programming.

IAP (In-Application Programming): The IAP is the ability to re-program the Flash memory

of a microcontroller while the user program is running.

ICP (In-Circuit Programming): The ICP is the ability to program the Flash memory of a

microcontroller using JTAG protocol while the device is mounted on the user application

board.

The Flash memory can be protected against different types of unwanted access

(read/write/erase). There are two types of protection:

●Sector Write Protection

●Flash Debug Protection (locks JTAG access)

Refer to the STR7 Flash Programming Reference manual for details.

Optional External Memory (STR710)

The non-multiplexed 16-bit data/24-bit address bus available on the STR710 (144-pin)

supports four 16-Mbyte banks of external memory. Wait states are programmable

individually for each bank allowing different memory types (Flash, EPROM, ROM, SRAM

etc.) to be used to store programs or data.

Figure 1 shows the general block diagram of the device family.

Flexible Power Management

To minimize power consumption, you can program the STR710 to switch to SLOW, WAIT,

LPWAIT (low power wait), STOP or STANDBY mode depending on the current system

activity in the application.

Flexible Clock Control

Two external clock sources can be used, a main clock and a 32 kHz backup clock. The

embedded PLL allows the internal system clock (up to 66 MHz) to be generated from a main

clock frequency of 16 MHz or less. The PLL output frequency can be programmed using a

wide selection of multipliers and dividers. The microcontroller core, APB1 and APB2

peripherals are in separate clock domains and can be programmed to run at different

frequencies during application runtime. The clock to each peripheral is gated with an

Introduction STR71xF

6/74

individual control bit to optimize power usage by turning off peripherals any time they are not

required.

Voltag e Regulators

The STR710 requires an external 3.0-3.6V power supply. There are two internal Voltage

Regulators for generating the 1.8V power supply for the core and peripherals. The main VR

is switched off during low power operation.

Low Voltage Detectors

Each voltage regulator has an embedded LVD that monitors the internal 1.8V supply. If the

regulated voltage drops below a certain threshold, the LVD will reset the STR710. This

enhances the security of the system by preventing the MCU from going into an

unpredictable state.

An external reset circuit must be used to provide the RESET at V33 power-up. It is not

sufficient to rely on the RESET generated by the LVD in this case. This is because LVD

operation is guaranteed only when V33 is within the specification.

1.2 On-Chip Peripherals

CAN Interface (STR710 and STR712)

The CAN module is compliant with the CAN specification V2.0 part B (active). The bit rate

can be programmed up to 1 MBaud.

USB Interface (STR710 and STR711)

The full-speed USB interface is USB V2.0 compliant and provides up to 16 bidirectional/32

unidirectional endpoints, up to 12 Mb/s (full-speed), support for bulk transfer, isochronous

transfers and USB Suspend/Resume functions.

Standard Timers

Each of the four timers have a 16-bit free-running counter with 7-bit prescaler

Three timers each provide up to two input capture/output compare functions, a pulse

counter function, and a PWM channel with selectable frequency.

The fourth timer is not connected to the I/O ports. It can be used by the application software

for general timing functions.

Realtime Clock (RTC)

The RTC provides a set of continuously running counters driven by the 32 kHz external

crystal. The RTC can be used as a general timebase or clock/calendar/alarm function.

When the STR710 is in Standby mode the RTC can be kept running, powered by the low

power voltage regulator and driven by the 32 kHz external crystal.

UARTs

The 4 UARTs allow full duplex, asynchronous, communications with external devices with

independently programmable TX and RX baud rates up to 1.25 Mb/s.

Smart Card Interface

UART1 is configurable to function either as a general purpose UART or as an asynchronous

Smart Card interface as defined by ISO 7816-3. It includes Smart Card clock generation and

provides support features for synchronous cards.

STR71xF Introduction

7/74

Buffered Serial Peripheral Interfaces (BSPI)

Each of the two SPIs allow full duplex, synchronous communications with external devices,

master or slave communication at up to 5.5Mb/s in Master mode and 4 Mb/s in Slave mode.

I2C Interfaces

The two I2C Interfaces provide multi-master and slave functions, support normal and fast

I2C mode (400 kHz) and 7 or 10-bit addressing modes.

One I2C Interface is multiplexed with one SPI, so either 2xSPI+1x I2C or 1xSPI+2x I2C may

be used at a time.

HDLC interface

The High Level Data Link Controller (HDLC) unit supports full duplex operation and NRZ,

NRZI, FM0 or MANCHESTER protocols. It has an internal 8-bit baud rate generator.

A/D Converter

The Analog to Digital Converter, converts in single channel or up to 4 channels in single-

shot or round robin mode. Resolution is 12-bit with a sampling frequency of up to 1 kHz. The

input voltage range is 0-2.5V.

Watchdog

The 16-bit Watchdog Timer protects the application against hardware or software failures

and ensures recovery by generating a reset.

I/O Ports

The 48 I/O ports are programmable as Inputs or Outputs.

External Interrupts

Up to 14 external interrupts are available for application use or to wake-up the application

from STOP mode.
