5M240ZT144C4N Ringkasan

The Intel (formerly Altera) 5M240ZT144C4N is a MAX V family Complex Programmable Logic Device (CPLD) with 192 macro cells and a maximum user I/O count suitable for industrial glue-logic and bus-interface bridging. It is supplied in a 144-pin TQFP (T144) package, operates from a 1.8 V core supply, and is specified over the commercial 0 C to +85 C temperature range, indicated by the "C4" speed-grade/temperature suffix. According to the manufacturer datasheet, the device integrates 240 logic elements (LE-equivalent macro cells), a non-volatile flash configuration memory, and an on-chip voltage regulator for the JTAG and core logic blocks, enabling instant-on behavior without an external configuration PROM.

A CPLD (Complex Programmable Logic Device) is a non-volatile, deterministic-latency programmable logic device sitting in the hierarchy: programmable logic -> CPLD -> non-volatile logic -> glue logic. It differs from an FPGA (volatile, register-rich, RAM-based) by retaining configuration in on-chip flash, providing sub-nanosecond pin-to-pin propagation delays, and offering hundreds rather than thousands of logic cells. CPLDs are typically deployed for I/O expansion, address decoding, bus interfacing (PCI, ISA, memory/flash controllers), and state-machine replacement where instant-on and deterministic timing are mandatory.

Key features of the 5M240ZT144C4N include 192 macro cells, 4.5 ns maximum pin-to-pin delay (C4 speed grade), a 1.8 V core supply with 3.3 V/2.5 V capable LVCMOS/LVTTL user I/O banks, JTAG 1149.1 boundary-scan programming, and on-chip flash memory enabling zero in-system configuration time. The device supports multi-volt core/I/O operation through internal level shifting, eliminating external translator ICs in mixed-voltage designs. The 144-pin TQFP footprint provides a generous I/O count for legacy parallel-bus bridging roles.

The MAX V architecture combines a Lab/Logic Array Block (LAB) fabric with a MultiTrack interconnect, paired with a flash-backed configuration cell array. This dual-storage approach gives the 5M240ZT144C4N single-chip, instant-on behavior ideal for boot-ROM replacement, power-sequencing controllers, and safety-critical state machines where an FPGA's configuration-boot time would violate system timing budgets.

Typical applications include I/O expansion and bus decoding in industrial control, address/data bus multiplexing for legacy microcontrollers and DSPs, glue-logic replacement for discrete 74-series TTL/CMOS gates, JTAG chain management and boundary-scan bridging, and FPGA configuration memory controllers. The MAX V family is also widely used as a system-level power-sequencer in board-management designs.

When designing with this part, allocate JTAG TMS, TCK, TDI, and TDO to a stable 1.8 V reference and add 0.1 uF ceramic bypass capacitors on every VCCIO/VCCINT pin. Observe the I/O-bank supply constraints - mixing 1.8 V and 3.3 V signaling requires separate VCCIO rails per bank. The 144-pin TQFP package is also offered in Pb-free and -I industrial temperature variants (5M240ZT144I5N), so verify the temperature suffix matches the deployment environment.
