Features summary

●

ARM7TDMI 16/32 bit RISC CPU based host microcontroller running at a frequency up

to 66 MHz.

●

Complete embedded memory system:

–

Flash 256 Kbytes + 16 Kbytes (100 KB erasing/programming cycles)

–

RAM 64 Kbytes.

●

External memory interface provides glueless support for up to four banks of external

SRAM, Flash, ROM.

●

High performance GPS engine (HPGPS).

●

ST Proprietary CMOS (0.18 µm) Flash embedded technology.

●

SBAS (WAAS and EGNOS) supported

●

-40 °C to 85 °C operating temperature range.

●

144-pin LFBGA package and 64-pin LQFP package

●

Power supply:

–

3.0 V to 3.6 V operating supply range for Input/Output periphery

–

3.0 V to 3.6 V operating supply range for A/D Converter reference

–

1.8 V operating supply range for core supply provided either by internal voltage

regulator (with external stabilization capacitor) or by external supply voltage.

●

Reset and clock control unit able to provide low power modes (WAIT, SLOW, STOP,

STANDBY) and to generate the internal clock from the external reference through

integrated PLL.

●

48 programmable general purpose I/O, each pin programmable independently as

digital input or digital output; 40 (30 in LQFP64) are multiplexed with peripheral

functions; 16 can generate an interrupt on input level/transition.

●

Real time clock module with 32 kHz low power oscillator and separate power supply to

continue running during standby mode.

●

16-bit Watchdog timer with 8 bits prescaler for system reliability and integrity.

●

2 CAN modules compliant with the CAN specification V2.0 part B (active) and bit rate

can be programmed up to 1 MBaud. One additional CAN at 1 Mbps (for STA2058 EM

SIP version)

●

Four 16-bit programmable timers with 7 bit prescaler, up to two input capture/output

compare, one pulse counter function, one PWM channel with selectable frequency

each.

●

4 channels 12-bit sigma-delta analog to digital converter, single channel or multi

channel conversion modes, single-shot or continuous conversion modes, sample rate

1 kHz, conversion range 0-2.5 V .

●

Three serial communication interfaces (UART) allow full duplex, asynchronous,

communications with external devices, independently programmable TX and RX baud

rates up to 625 Kbaud.

●

One UART adapted to suit smart card interface needs, for asynchronous SC as defined

by ISO 7816-3. It includes SC clock generation.

●

Two serial peripheral interfaces (SPI) allow full duplex, synchronous communications

with external devices, master or slave operation, max baud rate of 5.5 Mb/s. One SPI

may be used as multimedia card interface.
