This is an article about P85C220-10
The Intel 85C220 and 85C224 are 8‑micron CHMOS programmable logic devices offering up to 300 equivalent gates, 8 macrocells, and flexible I/O architecture. They are intended as high‑speed upgrades for SSI/MSI logic, bipolar PALs, and GAL devices in Intel microprocessor‑based systems.
Key features include maximum operating frequencies of 100 MHz (‑100) and 80 MHz (‑80), low power consumption (typical Icc ≈ 90 mA), up to 18 inputs and 8 outputs, and availability in 20‑pin, 24‑pin PDIP/CerDIP and 20‑pin/28‑pin PLCC packages. The devices provide low output skew (<300 ps) and programmable security bits for design protection.
