XA 16-bit microcontroller
32 K/1 K OTP/ROM/ROMless, 8-channel 8-bit A/D, low voltage (2.7 V–5.5 V),
I²C, 2 UARTs, 16 MB address range
Preliminary specification
XA-S3
GENERAL 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.
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.
• 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 V_DD.
• 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.
