XA-S3; XA 16-bit microcontroller 32K/1K OTP/ROM/ROMless, 8-channel 8-bit A/D, low voltage (2.7 V-5.5 V), I2C, 2 UARTs, 16MB address range
| Description |  |
The XA-S3 device is a member of Philips Semiconductors’ XA (eXtended Architecture) family of high performance 16-bit single-chip microcontrollers. The XA-S3 device combines 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.
| Features | |
|
- 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.
- High performance 8-channel 8-bit A/D converter with automatic channel scan and repeated read functions. Completes a conversion in 4.46 microseconds at 30 MHz. Alternate operating mode allows 10-bit conversion results.
- 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.
- 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.
- 50 I/O pins, each with 4 programmable output configurations.
- 30 MHz operating frequency at 2.7-5.5 V VDD over commercial operating conditions.
- 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.
