CMOS 8/16-BIT MICROPROCESSOR FAMILY
Features
• Advanced CMOS design for low power consumption
and increased noise immunity
• Emulation mode for total software compatibility
with 6502 designs
• Full 16-bit ALU, Accumulator, Stack Pointer,
and Index Registers
• Direct register for “zero page” addressing
• 24 addressing modes (including 13 original
6502 modes)
• Wait for Interrupt (WAI) and Stop the Clock (STP)
instructions for reduced power consumption and
decreased interrupt latency
• 91 instructions with 255 opcodes
• Co-Processor (COP) instruction and associated vector
• Powerful Block Move instructions
• Full 16-bit operation with 24 address lines for the
16 MByte memory
• Program selectable 8-bit mode for 6502 coding
compatibility Valid Program Address (VPA) and Valid
Data Address (VDA) outputs for dual cache and DMA
cycle steal implementation
• Vector Pull (VP) output indicates when interrupt
vectors are being fetched. May be used for
vectoring/prioritizing interrupts
• Abort interrupt and associated vector for interrupting
any instruction without modifying internal registers
• Memory Lock (ML) for multiprocessor system
implementation
• 40-pin DIP, 44-pin PLCC

Product Description
The G65SC816 is an advanced CMOS 16-bit microprocessor featuring total software compatibility with 8-bit NMOS and
CMOS 6500 series microprocessors. The G65SC816 provides 24 address lines for 16 Mbyte addressing, while providing
both 8-bit and 16-bit operation.
This microprocessor contains an Emulation (E) mode for emulating 8-bit NMOS and CMOS 6500 Series microprocessors.
A software switch determines whether the processor is in the 8-bit emulation mode or in the native 16-bit mode. This
allows existing 8-bit system designs to use the many powerful features of the G65SC816.
