Description: The MAX II CPLD has the following features:
■ Low-cost, low-power CPLD
■ Instant-on, non-volatile architecture
■ Standby current as low as 29 μA
■ Provides fast propagation delay and clock-to-output times
■ Provides four global clocks with two clocks available per logic array block (LAB)
■ UFM block up to 8 Kbits for non-volatile storage
■ MultiVolt core enabling external supply voltages to the device of either 3.3 V/2.5 V
or 1.8 V
■ MultiVolt I/O interface supporting 3.3-V, 2.5-V, 1.8-V, and 1.5-V logic levels-The MAX® II family of instant-on, non-volatile CPLDs is based on a 0.18-μm, 6-layermetal-
flash process, with densities from 240 to 2,210 logic elements (LEs) (128 to 2,210
equivalent macrocells) and non-volatile storage of 8 Kbits. MAX II devices offer high
I/O counts, fast performance, and reliable fitting versus other CPLD architectures.
Featuring MultiVolt core, a user flash memory (UFM) block, and enhanced in-system
programmability (ISP), MAX II devices are designed to reduce cost and power while
providing programmable solutions for applications such as bus bridging, I/O
expansion, power-on reset (POR) and sequencing control, and device configuration
control.
