PXAS33KFBE 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

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.

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.
