Description



Features:

·  Advanced fully static CMOS design for low power
     consumption and increased noise immunity
·  Wide operating voltage range, 1.8+/- 5%, 2.5+/- 5%,
     3.0+/- 5%, 3.3+/ - 10%, 5.0+/- 5% specified for use
     with advanced low voltage peripherals
·  Emulation mode allows complete hardware and
     software compatibility with 6502 designs
·  24-bit address bus provides access to 16 MBytes ofmemory space
·  Full 16-bit ALU, Accumulator, Stack Pointer and Index Registers
·  Valid Data Address (VDA) and Valid Program
     Address (VPA) output for dual cache and cycle steal
     DMA imple mentation
·  Vector Pull (VPB) output indicates when interrupt vectors are being addressed
·  Abort (ABORTB) input and associated vector supports processor repairs of bus error conditions
·  Low power consumption (300uA@1MHz)
·  Separate program and data bank registers allow
     program segmentation or full 16 MByte linear addressing
·  New Direct Register and stack relative addressing
     provides capability for re-entrant, re-cursive and relocatable programming
·  24 addressing modes - 13 original 6502 modes with 92 instructions using 256 OpCodes
·  Wait-for-Interrupt (WAI) and Stop-the-Clock (STP)
     instructions further reduce power consumption,
     decrease interrupt latency and allows synchronization with external events
·  Co-Processor (COP) instruction with associated vector
     supports co-processor configurations, i.e., floating point processors
·  Block move ability

Description

The W65C816S provides the design engineer with upward software compatibility from 8-bit W65C02 in applications to 16-bit system application. In Emulation mode, the W65C816S offers many advantages, including full software compatibility with 6502 coding.

Internal organization of the W65C816S can be divided into two parts: 1) The Register Section and 2) The Control Section. Instructions obtained from program memory are executed by implementing a series of data transfers within the Register Section. Signals that cause data transfers to be executed are generated within the Control Section. The W65C816S has a 16-bit internal bus architecture with an 8-bit external data bus and 24-bit external address bus.
