3 / 20 page STA2058 Features summary 3/20 1 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. |
