STR71xF - INTRODUCTION

4/49

Optional External Memory (STR710F)

The non-multiplexed 16-bit data/24-bit address bus available on the STR710F (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 STR71xF to switch to SLOW, WAIT

FOR INTERRUPT, 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 50 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.

Voltage Regulators

The STR71xF 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 and the Low Power VR switched on when the application puts the STR71xF in

Standby or Low Power Wait for Interrupt (LPWFI) mode.

Low Voltage Detectors

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

voltage drops below a certain threshold, the LVD will reset the STR71xF.

On-Chip Peripherals

CAN Interface (STR710F and STR712F)

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 (STR710F and STR711F)

The full-speed USB interface is USB V2.0 compliant and provides up to 8 bidirectional/16

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

Suspend/Resume functions.
