The document describes the features and characteristics of the products, including the brand and model information.
The G65SC816 family provides a 16‑bit ALU, 24 address lines for up to 16 MByte memory, and an emulation mode that ensures full software compatibility with 6502 designs. It includes features such as a full 16‑bit operation, block‑move instructions, and power‑saving WAI/STP instructions.
The datasheet lists pin assignments for the 40‑pin DIP and 44‑pin PLCC packages, ordering information, temperature range (‑40 °C to +85 °C), and performance designators of 4 MHz and 5 MHz. Package options and signal definitions such as VPA, VDA, and ABORT are also detailed.
| ALU width | 16‑bit |
|---|---|
| Address lines | 24 (16 MByte addressing) |
| Instruction count | 91 instructions (255 opcodes) |
| Package options | 40‑pin DIP, 44‑pin PLCC |
| Operating speed options | 4 MHz, 5 MHz |
It provides total software compatibility with 6502 designs, allowing existing 8‑bit code to run on the processor.
The processor supports 24 addressing modes, including the original 13 modes from the 6502.
Pin 7 (vpaAL_7) is assigned to the VPA signal.
The device operates from –40 °C to +85 °C.
