1 INTRODUCTION
The W65C816S is a low power cost sensitive 16-bit microprocessor. The variable length instruction set and manually
optimized core size makes the W65C816S an excellent choice for low power System-on-Chip (SoC) designs. The Verilog RTL
model is available for ASIC design flows. WDC, a Fabless Semiconductor Company, provides packaged chips for evaluation
or volume production. To aid in system development, WDC provides a Development System that includes a W65C816DB
Developer Board, an In-Circuit Emulator (ICE) and the W65cSDS Software Development System, see
www.westerndesigncenter.com for more information.
The WDC W65C816S is a fully static CMOS 16-bit microprocessor featuring software compatibility* with the 8-bit NMOS
and CMOS 6500-series predecessors. The W65C816S extends addressing to a full 16 megabytes. These devices offer the
many advantages of CMOS technology, including increased noise immunity, higher reliability, and greatly reduced power
requirements. A software switch determines whether the processor is in the 8-bit "emulation" mode, or in the native mode, thus
allowing existing systems to use the expanded features.
As shown in the W65C816S Processor Programming Model, Figure 2-2, the Accumulator, ALU, X and Y Index registers, and
Stack Pointer register have all been extended to 16 bits. A new 16-bit Direct Page register augments the Direct Page addressing
mode (formerly Zero Page addressing). Separate Program Bank and Data Bank registers provide 24-bit memory addressing
with segmented or linear addressing.
Four new signals provide the system designer with many options. The ABORTB input can interrupt the currently executing
instruction without modifying internal register, thus allowing virtual memory system design. Valid Data Address (VDA) and
Valid Program Address (VPA) outputs facilitate dual cache memory by indicating whether a data segment or program segment
is accessed. Modifying a vector is made easy by monitoring the Vector Pull (VPB) output.
KEY FEATURES OF THE W65C816S
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 of
memory 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 implementation
Vector Pull (VPB) output indicates when interrupt
vectors are being addressed
Abort (ABORTB) input and associated vector supports
processor repairs of bus error conditions
*
Except for the BBRx, BBSx, RMBx, and SMBx bit manipulation instructions which do not exist for the W65C816S
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 re-
locatable 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
