M4A5-64/32-55VC

M4A5-64/32-55VC is a complex programmable logic device (CPLD) developed by Altera Corporation. It is a highly integrated circuit with internal RAM, ROM and analog functions. The M4A5-64/32-55VC device is composed of a field-programmable array of programmable logic blocks and supporting I/O cells. It has four phases of the embedded-instructions fetch (IF) step: fetch, decode, execute, and output.

The M4A5-64/32-55VC CPLD has an integrated architecture that integrates the logic blocks, routing switches and clock networks into a single die. The logic blocks can be programmed to perform simple logic functions such as AND/OR gates, function blocks, or to create more complex logic. The integrated architecture is designed to reduce power consumption and increase the ease of programming.

The device also includes a wide range of I/O structures, including interrupt structures, memory interface structures, clock sources and PLLs. In addition, the device can support up to 8 JTAG or dual-port debug ports. All these features make the M4A5-64/32-55VC CPLD an ideal solution for embedded applications that require the highest level of integration.
