General Description

The EPROM-based EP220 and EP224 devices feature a flexible I/O architecture and implement 150 usable (300 available) gates of custom user logic functions. EP220 and EP224 devices can be used as upgrades for high-speed bipolar programmable logic devices (PLDs) or for 74-series LS and CMOS (SSI and MSI) logic devices in high-performance microcomputer systems.

Features

■ High-performance, low-power Erasable Programmable Logic Devices (EPLDs) with 8 macrocells

– Combinatorial speeds as low as 7.5 ns

– Counter frequencies of up to 100 MHz

– Pipelined data rates of up to 115 MHz

– Maximum 5.5-ns Clock-to-output time; minimum 4.5-ns setup time

■ Replacement or upgrade for 16V8/20V8 PAL and GAL devices

■ Up to 18 inputs (10 dedicated inputs) in EP220, 22 inputs (14 dedicated inputs) in EP224; up to 8 outputs in both EP220 and EP224

■ Macrocells independently programmable for both registered and combinatorial logic

■ Programmable inversion control supporting active-high or activelow outputs

■ Low power consumption

– Typical ICC = 90 mA at 25 MHz (for -7A speed grades)

– Quarter-power mode (ICC = 40 mA)

– Programmable zero-power mode with typical ICC = 50 μA (for -10A and -12 speed grades)

■ Programmable Security Bit for total protection of proprietary designs

■ Low output skew for Clock driver applications

■ 100 generically tested to provide 100 programming yield

■ Software and programming support from Altera and a wide range of third-party tools

■ Available in windowed ceramic and one-time-programmable (OTP) plastic packages

– 20-pin plastic J-lead package (PLCC)

– 20-pin ceramic and plastic dual in-line packages (CerDIP and PDIP)

– 24-pin PDIP

– 28-pin PLCC
