DESCRIPTION The XA-S3 device is a member of Philips Semiconductors’ XA (e Xtended Architecture) family of high performance 16-bit single-chip microcontrollers. The XA-S3 device bines many powerful peripherals on one chip. With its high performance A/D converter, timers/counters, watchdog, Programmable Counter Array (PCA), I2C interface, dual UARTs, and multiple general purpose I/O ports, it is suited for general multipurpose high performance embedded control functions. - Three standard counter/timers with enhanced features . All timers have a toggle output capability. - Watchdog timer. - 5-channel 16-bit Programmable Counter Array (PCA). - I2C-bus serial I/O port with byte-oriented master and slave functions. Specific features of the XA-S3 - 2.7 V to 5.5 V operation. - 32 K bytes of on-chip EPROM/ROM program memory. - 1024 bytes of on-chip data RAM. - Supports off-chip addressing up to 16 megabytes (24 address lines). A clock output reference is added to simplify external bus interfacing. - Two enhanced UARTs with independent baud rates. - Seven software interrupts. - Active low reset output pin indicates all reset occurrences (external reset, watchdog reset and the RESET instruction). A reset source register allows program determination of the cause of the most recent reset. - High performance 8-channel 8-bit A/D converter with automatic channel scan and repeated read functions. pletes a conversion in 4.46 microseconds at 30 MHz. Alternate operating mode allows 10-bit conversion results. - 50 I/O pins, each with 4 programmable output configurations. - 30 MHz operating frequency at 2.7- 5.5 V VDD. - Power saving operating modes: Idle and Power-down. Wake-up from power-down via an external interrupt is supported. - 68-pin PLCC and 80-pin PQFP packages.
