MACH231-6JC

Complex Programmable Logic Devices Overview

The MACH231-6JC is a high-performance Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's MACH family. It features 32 macrocells and supports up to 24 I/O pins within a 40-pin PLCC package. The device operates with a maximum system clock frequency of 65 MHz and utilizes Lattice's proprietary ispMACH technology for non-volatile configuration. Key electrical parameters include a supply voltage range of 2.7V to 3.6V and an operating temperature range of -40°C to +85°C. It offers fast propagation delays of 6.5 ns, ensuring reliable logic execution in embedded control applications.

• Memory interface management for legacy or specialized storage devices
• Logic replacement for discrete gate arrays in space-constrained designs

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '6JC' against the manufacturer's current datasheet to confirm pin compatibility and speed grade. Ensure the procurement channel provides genuine components with intact lead frames, as PLCC packages are susceptible to bent pins during handling. Confirm RoHS compliance status if required by local regulations, noting that older MACH series parts may have varying environmental declarations depending on the manufacturing batch date code.

Complex Programmable Logic Devices Selection Notes

Select the MACH231-6JC when design requirements demand moderate logic density with low pin count and instant-on capability. Compare against the MACH210 series for lower complexity needs or the MACH250 series for increased macrocell resources. Consider the package type; the PLCC-40 offers robust mechanical stability but requires specific socketing or surface-mount techniques. Evaluate power constraints, as this device operates at 3.3V, which may necessitate level shifting if interfacing with 5V legacy systems.

Complex Programmable Logic Devices Part Context

The MACH231 belongs to the second generation of Lattice's ispMACH CPLDs, introduced to bridge the gap between simple GAL replacements and larger FPGA solutions. This series was designed to offer higher density than the original MACH100/200 lines while maintaining deterministic timing and non-volatility. It represents a transitional product line before the widespread adoption of the MachXO and CrossLink families, often found in established industrial and communication equipment designs requiring reliable, fixed-function logic.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary nature of the MACH architecture. Potential substitutes include the Lattice MACH210 or MACH250 series if resource allocation allows. For generic logic replacement, verify if the application can be mapped to modern low-power CPLDs such as the Lattice iCE40 or MachXO3L, though these require reconfiguration of the design flow and potentially different packaging.
