M4A3-32/32-10VC48

Complex Programmable Logic Devices Overview

The M4A3-32/32-10VC48 is a member of the ispMACH 4A family, a high-performance E2CMOS Complex Programmable Logic Device (CPLD). It operates at 3.3 V and features 32 macrocells with a 1:1 macrocell-to-I/O cell ratio, providing 32 user I/Os. The device supports in-system programming via JTAG (IEEE 1149.1) and offers guaranteed fixed timing through SpeedLocking technology. Key electrical parameters include a maximum propagation delay ($t_{PD}$) of 5.0 ns and a maximum count frequency ($f_{CNT}$) of 182 MHz.

Complex Programmable Logic Devices Feature Summary

• High-speed performance with 5.0 ns $t_{PD}$ and 182 MHz $f_{CNT}$ using SpeedLocking for up to 20 product terms per output.
• Flexible architecture with 32 macrocells, central switch matrix, and input/output switch matrices ensuring 100% routability.
• Supports synchronous and asynchronous modes with D/T registers, latches, and programmable polarity.
• JTAG compliant for boundary scan testing and in-system programming.

Complex Programmable Logic Devices Applications

• General-purpose logic replacement
• Bus bridging and protocol conversion
• Address decoding and control logic

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '48' against official Lattice documentation to confirm package type and temperature grade, as standard datasheets list TQFP, PLCC, PQFP, BGA, fpBGA, and caBGA options without explicitly detailing the '48' designation. Confirm RoHS compliance status for this specific ordering code.

Complex Programmable Logic Devices Selection Notes

Select this device for designs requiring 32 macrocells with a 1:1 macrocell-to-I/O ratio. Ensure the design utilizes up to 20 product terms per output to leverage the guaranteed 5.0 ns speed. Verify that the system voltage is compatible with 3.3 V operation and that mixed-voltage safety features are utilized if interfacing with 5 V inputs.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which includes both 3.3 V (M4A3) and 5 V (M4A5) variants. The M4A3-32/32 variant specifically denotes a 32-macrocell device with a 1:1 macrocell-to-I/O ratio, distinguishing it from the 2:1 ratio devices like the M4A3-64/32.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consider other members of the ispMACH 4A family or the subsequent ispMACH 4A SP family for pin-compatible or functionally similar replacements, subject to verification of specific package and speed grades.
