ARM7TDMI 16/32 bit RISC CPU based host microcontroller running at a frequency up
to 66 MHz.
Complete embedded memory system:
–
–
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:
–
–
–
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.
Flash 256 Kbytes + 16 Kbytes (100 KB erasing/programming cycles)
RAM 64 Kbytes.
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.
