High-performance 3.3-V EEPROM-based programmable logic
devices (PLDs) built on second-generation Multiple Array MatriX
(MAX®) architecture (see Table 1)
■ 3.3-V in-system programmability (ISP) through the built-in
IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface with
advanced pin-locking capability
– MAX 7000AE device in-system programmability (ISP) circuitry
compliant with IEEE Std. 1532
– EPM7128A and EPM7256A device ISP circuitry compatible with
IEEE Std. 1532
■ Built-in boundary-scan test (BST) circuitry compliant with
IEEE Std. 1149.1
■ Supports JEDEC Jam Standard Test and Programming Language
(STAPL) JESD-71
■ Enhanced ISP features
– Enhanced ISP algorithm for faster programming (excluding
EPM7128A and EPM7256A devices)
– ISP_Done bit to ensure complete programming (excluding
EPM7128A and EPM7256A devices)
– Pull-up resistor on I/O pins during in-system programming
■ Pin-compatible with the popular 5.0-V MAX 7000S devices
■ High-density PLDs ranging from 600 to 10,000 usable gates
■ Extended temperature range
