M4A3-32/32-10VI48

Complex Programmable Logic Devices Overview

The M4A3-32/32-10VI48 is a Complex Programmable Logic Device (CPLD) from the ispMACH 4A family, manufactured by Lattice Semiconductor. It operates at a 3.3-V supply voltage and features 32 macrocells with a 1:1 macrocell-to-I/O cell ratio. The device provides 32 user I/Os and supports a maximum operating frequency of 182 MHz. Key electrical parameters include a propagation delay ($t_{PD}$) of 5.0 ns, an output clock skew ($t_{COS}$) of 4.0 ns, and a setup time ($t_{SS}$) of 3.0 ns. It utilizes EEPROM technology for non-volatile configuration and includes JTAG boundary scan compliance.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I48' against official documentation to confirm package type and temperature grade. Confirm current availability status as older CPLD families may have limited stock or end-of-life implications. Ensure design tools support the ispMACH 4A family for successful implementation.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 32 macrocells with a 1:1 macrocell-to-I/O ratio. The -10 speed grade offers a 5.0 ns $t_{PD}$ suitable for high-speed logic. Consider the 48-pin TQFP package if space constraints align with its dimensions. Verify power consumption requirements against the 20 mA static current specification.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which blends ispLSI 2000 and ispMACH 4A architectures. It is designed for rapid logic development with excellent First-Time-Fit characteristics. The family supports densities from 32 to 512 macrocells across various packages including PLCC, PQFP, TQFP, BGA, fpBGA, and caBGA.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same density and package are not explicitly listed in the provided datasheet. Cross-model migration within the ispMACH 4A family requires verification of pin-out retention and macrocell-to-I/O ratios. Consult Lattice Semiconductor for current alternative part numbers.
