5M1270ZT144I5N Ringkasan

The Intel / Altera (formerly Altera) 5M1270ZT144I5N is a MAX V family Complex Programmable Logic Device (CPLD) that delivers 980 macro cells, 212 user I/O pins, and a 201.1 MHz internal operating frequency in a 144-pin TQFP package. It is built on a low-power, non-volatile flash process that retains configuration without an external boot PROM, and operates from a 1.8 V core supply with 1.2 V/3.3 V multi-voltage I/O support for direct interface to legacy and modern logic families.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocells with a centralized interconnect fabric. In the broader programmable logic hierarchy it sits below FPGAs in density and above simple SPLDs in logic capacity, and is widely used as glue logic, interface bridges, and power-up controllers where instant-on deterministic behavior is required. The MAX V family uses a flash-based configuration cell, so the device is live within microseconds of power-up rather than milliseconds, which differentiates it from SRAM-based FPGAs that must load bitstreams at every boot.

Key features of the 5M1270ZT144I5N include 980 logic elements (LEs), 8 Kbits of user flash memory, on-chip voltage regulation supporting 1.8 V to 3.3 V I/O standards, JTAG (IEEE 1149.1) and in-system programmability via the Altera/Intel Quartus toolchain, and an industrial operating temperature range of -40C to +100C (I-temp grade, indicated by the 'I' in the part number). The 144-pin TQFP package provides a 0.5 mm pitch and supports surface-mount assembly with standard reflow profiles, making it suitable for high-volume PCB manufacturing.

From an architecture standpoint, the 5M1270ZT144I5N uses a Logic Array Block (LAB) structure with 980 macrocells distributed across multiple LABs, each containing 16 macrocells. The non-volatile flash configuration makes the device suitable for safety-critical boot logic, since configuration cannot be lost due to brown-outs or in-rush transients. Combined with deterministic 1.5 ns pin-to-pin propagation delays through the central switch matrix, the part is well suited to high-speed glue logic between processors, memory, and peripherals.

Typical applications for the 5M1270ZT144I5N include I/O expansion and level shifting in industrial controllers, address decoding and bus glue logic for legacy 5 V and 3.3 V microprocessor systems, power-up sequencing and supervisory logic, custom peripheral interfaces in embedded designs, and LED display or motor-control timing logic. The combination of low power, instant-on behavior, and high I/O count also makes it attractive as a cost-effective bridge between processors and slow-speed peripherals.

When designing with this part, follow Intel/Altera's Quartus II or Quartus Prime power estimation and pin assignment guidelines carefully: the 144-pin TQFP has a maximum of 212 usable I/O pins, so high-fanout designs should budget for the JTAG chain and global clock pins before allocating GPIO. Decoupling should follow the reference schematic with 0.1 uF and 10 uF capacitors placed within 100 mils of each supply pin to keep the internal 1.8 V regulator stable under dynamic load.

This page synthesizes distributor pricing, drop-in alternatives in the same 144-TQFP footprint, and practical Quartus design notes not found in the standalone datasheet, giving procurement and engineering teams a single decision-ready reference.
