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.

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
