This is the listing from the Catalog I received from WDC:
 
The W65C256S CMOS 16-bit Microcomputer is a computer fully static 16-bit
microcomputer and complements the W65C816S 16 bit microprocessor. The
following features make the W65C265S a leading candidate for 16 bit
microcomputer applications:

Key features: CMOS low power process with microamp standby current.
*Wide operating voltage range,1.0-6.0v * W65c816s compatiable CPU 
* Single chip microcomputer: 2 tone generators: 64 CMOS compatible I/O
lines; 8k x8 ROM; 576 x 8 RAM; fast oscillator start and stop feature
* 16 Mbyte linear address space * Twenty-nine priority encoded interrups
* Four UART's * Time of Day (TOD) clock features * 8 x 16 bit timer/counter
* Bus control Register * 8 programmable chip slect outputs * Industry
standard development support tools for all languages * Power managment.

Features                  W65c256s
