The 5M160ZE64A5N is a MAX V CPLD (Complex Programmable Logic Device) from Intel/Altera in 64-ball MBGA (5x5mm), with 160 macrocells and 54 I/O pins. The MAX V architecture uses a Flash-based configuration, meaning the device is instantly on at power-up (no external configuration ROM needed), unlike FPGAs that require milliseconds to load from serial Flash. Each macrocell contains: a 4-input look-up table (LUT) implementing any 4-variable Boolean function; a programmable flip-flop (D/T/JK/SR); and clock enable, synchronous/asynchronous preset/clear controls. The 160 macrocells are organized into 10 Logic Array Blocks (LABs) of 16 macrocells each, interconnected by a programmable routing matrix. The MultiTrack interconnect provides fixed delays between any two points, making timing predictable and deterministic (unlike FPGAs with variable routing delays). The device includes a built-in Flash memory (8Kbit user Flash for storing non-volatile data like calibration constants) and a JTAG interface for in-system programming and boundary-scan testing. The 1.8V core voltage (VCCINT) minimizes power consumption, while VCCIO supports 1.5V, 1.8V, 2.5V, and 3.3V I/O standards. The zero-power idle mode draws less than 10uA, making MAX V suitable for always-on applications. The -A5 suffix specifies the speed grade (5ns pin-to-pin delay). The MBGA-64 package at 5x5mm is the smallest footprint for 160 macrocells. Applications include: I2C/SPI bridging, voltage-level translation, glue logic consolidation, power-supply sequencing, and bus arbitration.
