G65SC802
G65SC816
CMOS 8-Bit/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
Features (G65SC802 Only)
• 8-Bit Mode with both software and hardware (pin-to-pin) com­
patibility with 6502 designs (64 KByte memory space)
• Program selectable 16-bit operation
• Choice of external or on-board clock generation
Features (G65SC816 Only)
• Full 16-bit operation with 24 address lines for 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
General Description
The G65SC802 and G65SC816 are ADV-CMOS (ADVanced CMOS) 16-
bit microprocessors featuring total software compatibility with 8-bit
NMOS and CMOS 6500 series microprocessors. The G65SC802 is pin-
to-pin compatible with 8-bit 6502 devices currently available, while also
providing full 16-bit internal operation. The G65SC816 provides 24 ad­
dress lines for 16 MByte addressing, while providing both 8-bit and 16-bit
operation.
Each 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 G65SC802 and G65SC816.
The G65SC802 and G65SC816 provide the system engineer with many
powerful features and options. A 16-bit Direct Page Register is provided
to augment the Direct Page addressing mode, and there are separate
Program Bank Registers for 24-bit memory addressing. Other valuable
features include:
• An Abort input which can interrupt the current instruction without
modifying internal registers.
• Valid Data Address (VDA) and Valid Program Address (VPA) outputs
which facilitate dual cache memory by indicating whether a data or
program segment is being accessed.
• Vector modification by simply monitoring the Vector Pull (VP) output.
• Block Move instructions.
GTE Microcircuits’ G65SC802and G65SC816 microprocessors offer the
design engineer a new freedom of design and application, and the many
advantages of state-of-the-art ADV-CMOS technology.

This device contains input protection against damage due to high static
voltages or electric fields; however, precautions should be taken to avoid
application of voltages higher than the maximum rating.
Notes:
1. Exceeding these ratings may cause permanent damage. Functional
operation under these conditions is not implied.
