M4A5-64/32-10VNC48

Complex Programmable Logic Devices Overview

The M4A5-64/32-10VNC48 is a 5-V ispMACH 4A CPLD featuring 64 macrocells and 32 I/Os in a 48-pin TQFP package. It operates within a 4.75 V to 5.25 V supply range, supporting a maximum frequency of 167 MHz with a typical propagation delay of 5.5 ns. The device utilizes EEPROM technology for non-volatile configuration and supports JTAG-based in-system programming. Designed for commercial applications between 0°C and +70°C, it ensures 100% pin-out retention and includes features like programmable polarity and individual output slew rate control.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'VNC48' against official Lattice documentation to confirm package type and temperature grade. Confirm RoHS compliance status as datasheet availability varies by revision. Check for end-of-life notifications or product change notices prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 5-V operation with high-density logic (64 macrocells). Ensure the design fits within the 32 I/O constraint. Consider the 5.5 ns delay for timing closure. Verify that the 48-pin TQFP footprint matches the PCB layout requirements.

Complex Programmable Logic Devices Part Context

Part of the ispMACH 4A family, which offers flexible architecture with central switch matrices. This series bridges older MACH 4 devices and newer ECP/FPGA lines, providing cost-effective solutions for medium-complexity logic applications with high routability.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements may include other speed grades within the M4A5-64/32 series, such as M4A5-64/32-5VC or M4A5-64/32-7VC, provided timing requirements are met. Cross-family migration to M4A3 requires voltage level adjustment.
