Infineon Technologies CY37064VP100-100AXCT

Overview

CY37064VP100-100AXCT from Cypress Semiconductor is a 64-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, operating at 3.3V with 100-pin TQFP packaging. It delivers 143 MHz maximum frequency, 8.5 ns propagation delay, supports up to 64 I/O pins, and features four synchronous clocks, programmable bus-hold on all I/Os, and JTAG-compliant ISR for field reconfiguration without pinout or timing changes - used in PCI-compliant interface logic and legacy system glue logic.

For engineers reviewing the CY37064VP100-100AXCT datasheet, CY37064VP100-100AXCT pinout, CY37064VP100-100AXCT application, or CY37064VP100-100AXCT equivalent, key selection criteria include macrocell count, I/O count per package, tPD/fMAX speed bin, VCCO voltage tolerance (3.3V/5V), and JTAG boundary-scan compliance for production testability and in-system updates.

Technical Context

The CY37064VP100-100AXCT implements a modular architecture with two logic blocks, each containing a 72×87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells (mix of I/O and buried). Its Programmable Interconnect Matrix (PIM) provides 36 global inputs per logic block with no route-dependent delays - all timing parameters are fixed and worst-case PIM delay is embedded in tPD spec.

It supports flexible clocking: four global synchronous clocks (CLK0–CLK3) with polarity control, plus one asynchronous product-term clock (PTCLK); all I/Os feature programmable slew rate (fast/slow) and bus-hold capability; dedicated input/clock pins enable direct clock distribution with configurable edge sensitivity.

FAQ

What is the difference between CY37064VP100-100AXCT and CY37064V-100AXCT?

The "P" in CY37064VP100-100AXCT explicitly denotes the 100-pin TQFP package (P = Plastic TQFP), while CY37064V-100AXCT is a generic part number without package suffix. The full orderable part confirms 100-pin TQFP, RoHS-compliant, 3.3V operation, and -100 speed grade (143 MHz fMAX). Package-specific marking ensures correct footprint and thermal performance in layout.

Does CY37064VP100-100AXCT support 5V I/O signaling?

No - CY37064VP100-100AXCT is a 3.3V-core device with 3.3V I/O (VCCO = 3.3V) and 5V-tolerant inputs only. Outputs swing to 3.3V CMOS levels and cannot drive 5V TTL loads directly. For true 5V I/O, the 5V-supply CY37064-100AXCT variant must be used, which accepts 5V VCCO and provides 5V-compatible outputs.

Can this device replace a 22V10 PLD in existing designs?

Yes - the Ultra37000 architecture extends the 22V10's simplicity to higher densities: same macrocell structure (D/T/L flip-flop, OE control, product-term clocking), identical JTAG programming flow, and backward-compatible HDL synthesis. Migration requires only pin mapping and timing constraint updates - no logic redesign needed for functionally equivalent 22V10 implementations scaled to 64 macrocells.

Is boundary-scan testing supported out-of-the-box?

Yes - CY37064VP100-100AXCT implements full IEEE 1149.1 boundary-scan with mandatory TCK/TMS/TDI/TDO/TRST# pins and internal scan chain covering all I/Os and JTAG controller logic. No additional configuration is required; standard boundary-scan tools (e.g., JTAG Live, Goepel) detect the device ID and execute EXTEST, SAMPLE/PRELOAD, and BYPASS instructions immediately after power-up.
