M4A3-32/32-12VI48

Complex Programmable Logic Devices Overview

The M4A3-32/32-12VI48 is a member of the ispMACH 4A family, a high-performance E2CMOS Complex Programmable Logic Device (CPLD). It operates at 3.3 V and contains 32 macrocells with 32 user I/O options in a 48-pin TQFP package. The device features a maximum propagation delay of 12 ns and a maximum operating frequency of 182 MHz. It utilizes EEPROM technology for non-volatile configuration and supports JTAG boundary scan testing.

Complex Programmable Logic Devices Feature Summary

• SpeedLocking performance guarantees fixed timing delays independent of logic complexity.
• Central switch matrix ensures 100% routability and pin-out retention across design iterations.
• Supports synchronous and asynchronous modes with D/T registers and latches.
• Compliant with IEEE 1149.1 JTAG standard for in-system programming and boundary scan.

Complex Programmable Logic Devices Applications

• PCI compliant interface designs
• Mixed supply voltage system integration
• High-speed logic control requiring predictable timing

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'I48' corresponds to the 48-pin TQFP package and commercial temperature range. Confirm the datasheet revision matches the required specifications. Check for lead-free package availability if environmental compliance is mandatory. Ensure the source document explicitly lists this part number variant.

Complex Programmable Logic Devices Selection Notes

Select this component when 32 macrocells are sufficient for the design logic. The -12 speed grade provides a 12 ns delay suitable for moderate-speed applications. Verify that the 48-pin TQFP package fits the board layout constraints. Consider the 3.3 V operation requirement for power supply compatibility.

Complex Programmable Logic Devices Part Context

This device belongs to the ispMACH 4A family, which offers densities from 32 to 512 macrocells. The M4A3 series specifically denotes 3.3 V operation. The '32/32' designation indicates a 1:1 macrocell-to-I/O ratio. The family is known for its flexible architecture and first-time-fit capabilities.

Complex Programmable Logic Devices Replacement Considerations

Other devices within the M4A3-32 series with different speed grades or packages may be compatible if electrical parameters align. Verify pinout compatibility before substitution. No direct cross-model replacements are confirmed in the provided documentation.
