MACH211SP-20VC

Complex Programmable Logic Devices Overview

The MACH211SP-20VC is a high-density Electrically Erasable Programmable Logic Device (EE PLD) from the MACH 2 family, manufactured by Vantis Corporation. It features 64 macrocells and 32 I/O lines within a 44-pin Plastic Quad Flatpack (PQFP) package. The device operates on a single 5V supply and supports in-system programming via JTAG. With a maximum propagation delay of 20 ns, it offers a guaranteed fixed timing performance through Speed Locking technology. The component is designed for commercial temperature ranges and includes programmable power-down modes to manage power consumption effectively.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells with 32 I/Os and dedicated inputs/clocks

• Speed Locking technology for guaranteed fixed timing
• Bus-Friendly inputs and I/Os for improved signal integrity

Complex Programmable Logic Devices Applications

• High-speed data bus interface logic
• Address decoding and control logic in embedded systems
• PCI-compliant peripheral interfaces
• Complex glue logic replacement in digital designs

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'VC' corresponds to the 44-pin PQFP package and commercial temperature grade as per the official datasheet. Confirm RoHS compliance status, as earlier revisions may not meet current environmental standards. Ensure the supplier provides documentation confirming JTAG chain compatibility for in-system programming verification.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity and a 20 ns speed grade is required. Compare against the -7/10/12/15 variants if faster switching speeds are needed, or the -24JI variant for industrial temperature ranges. Ensure the PCB layout accommodates the 44-pin PQFP footprint and that the system voltage aligns with the 5V operating requirement.

Complex Programmable Logic Devices Part Context

The MACH211SP belongs to the MACH 2 family of EE CMOS programmable logic devices. This family is characterized by its ability to retain pin-outs during design changes, facilitating in-system programming without hardware redesign. The SP designation indicates enhanced performance features such as Speed Locking and Bus-Friendly I/Os compared to earlier generations.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other MACH211SP variants with different speed grades (e.g., MACH211SP-15VC) if timing constraints allow. Cross-family replacements from AMD/Xilinx CPLDs may require schematic and firmware adjustments due to architectural differences.
