PALCE24V10H-15PC

Overview

The PALCE24V10H-15PC is a high-performance Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's PALCE family. It features 24 macrocells and supports up to 108 I/O pins, providing substantial logic density for its class. The device operates with a maximum propagation delay of 15 ns and includes comprehensive in-system programmability via JTAG and SPI interfaces. Built on advanced CMOS technology, it offers low power consumption and robust ESD protection, making it suitable for general-purpose logic replacement and interface bridging applications where reliable, non-volatile configuration is required.

Feature Summary

• 24 Macrocells with 108 available I/O pins for complex logic implementation
• Maximum propagation delay of 15 ns for high-speed operation
• In-system programmability supporting JTAG and Serial Peripheral Interface (SPI)
• CMOS technology ensuring low power consumption and high noise immunity

Applications

• General-purpose logic replacement for legacy TTL/CMOS circuits
• Address decoding and chip select generation in embedded systems
• Interface bridging between different voltage domains or protocols
• State machine implementation in industrial control equipment

Procurement Notes

Verify the specific suffix 'H' and '15' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the programming requirements for JTAG/SPI are supported by your existing test fixtures. Check for any recent product change notices regarding package availability or lead-free compliance status before finalizing procurement.

Selection Notes

Select this component when a moderate number of macrocells (24) and a high count of I/Os (up to 108) are required. The 15 ns speed grade is suitable for mid-range clock frequencies. Consider alternative Lattice CPLDs if higher macrocell density or different I/O voltage levels are needed. Verify that the package type matches the PCB footprint constraints and thermal requirements of the target application.

Part Context

This part belongs to the PALCE series, which represents Lattice's high-density CPLD offerings designed for complex logic applications. It serves as a successor to earlier PAL/GAL devices, offering reprogrammability and higher integration. The PALCE family is widely used in industries requiring reliable, field-upgradable logic solutions without the complexity of FPGA design flows.
