5M570ZT144C4N

Overview

The Altera 5M570ZT144C4N is a Complex Programmable Logic Device (CPLD) belonging to the MAX V family. It features 440 macrocells and 570 logic elements, housed in a 144-pin Thin Quad Flat Package (TQFP). The device supports system-in-programmability via flash memory technology. It operates within a commercial temperature range of 0 °C to +85 °C and utilizes a single power supply voltage ranging from 1.71 V to 1.89 V. Key electrical parameters include a maximum propagation delay of 9.5 ns under 10 pF load conditions.

Feature Summary

• Contains 440 macrocells and 570 logic array blocks for digital logic implementation.
• Supports In-System Programming (ISP) using non-volatile flash memory configuration.
• Provides independent output enable control for each user I/O pin.
• Operates on a single 1.8 V supply rail with a specified range of 1.71 V to 1.89 V.

Applications

• Interface bridging between different voltage domains or protocol converters.
• Address decoding and bus arbitration in embedded systems.
• Simple state machine implementation for industrial control logic.
• Replacement for legacy GAL or PAL devices in existing designs.

Procurement Notes

Verify the specific suffix 'C4N' against the manufacturer's current datasheet to confirm the exact speed grade and package dimensions. Ensure the design accounts for the 144-TQFP thermal characteristics and moisture sensitivity levels during soldering processes. Confirm that the 1.8V core voltage requirement aligns with the target board's power distribution network.

Selection Notes

Select this component when a low-cost, low-power CPLD with flash-based reprogrammability is required. The 5M570Z variant offers higher density than the base 5M240 series but lower complexity than the 5M570ZT variants with extended temperature ranges. Verify that the 114 available user I/O pins meet the interface requirements of the application.

Part Context

This part belongs to the Intel (formerly Altera) MAX V family, designed as a cost-effective alternative to traditional SRAM-based FPGAs for simple logic applications. The MAX V series integrates flash memory to eliminate the need for external configuration chips, reducing bill-of-materials costs and board space compared to previous generations like the MAX II series.

Replacement Considerations

Direct functional equivalents within the same package and pinout may include other MAX V devices with similar macrocell counts, such as the 5M570ZT144I5N, though speed grades and temperature ranges differ. Cross-family replacements require careful verification of I/O voltage compatibility and pin assignments.
