Infineon Technologies CY37032VP44-100AXCT

Overview

CY37032VP44-100AXCT from Cypress Semiconductor is a 3.3V In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, featuring 32 macrocells, 5 dedicated inputs (including 4 clock pins), and 37 user I/Os in a 44-pin TQFP package. It supports 3.3V JEDEC CMOS output levels with 5V-tolerant I/Os, programmable bus-hold on all I/Os, and operates at tPD = 10 ns (fMAX = 100 MHz) in the 100 speed bin. It is used in legacy PCI-compliant interface logic, FPGA configuration glue logic, and industrial control state machines.

For engineers reviewing the CY37032VP44-100AXCT datasheet, CY37032VP44-100AXCT pinout, CY37032VP44-100AXCT application, or CY37032VP44-100AXCT equivalent, key selection criteria include its 3.3V supply operation, JTAG-based ISR capability, fixed pinout across density upgrades, programmable slew rate per output, and dedicated asynchronous set/reset product terms per logic block.

Technical Context

The device implements a modular architecture with one logic block containing a 72 × 87 product term array, intelligent product term allocator (0–16 terms/macrocell), and 16 macrocells-configured as either I/O or buried types. All signals route through a fully global Programmable Interconnect Matrix (PIM) with no route-dependent timing penalties.

It supports four synchronous clocks (CLK0–CLK3) plus one asynchronous product term clock (PTCLK), programmable clock polarity per logic block, and independent OE product term control for groups of eight macrocells. Bus-hold and slew-rate control are individually configurable per I/O pin.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a U.S.-based semiconductor company specializing in programmable logic, memory, and mixed-signal solutions for industrial, automotive, and communications markets.

The Ultra37000 CPLD family was designed to deliver high-density, pin-compatible, and timing-stable logic replacement for legacy 22V10-based designs-emphasizing in-system reprogrammability, fixed pinout migration paths, and simplified timing closure.

FAQ

Is CY37032VP44-100AXCT compatible with 5V logic systems?

Yes - all I/Os are 5V-tolerant when VCCO = 3.3V, allowing direct connection to 5V buses without level shifters. However, the device must be powered with 3.3V VCC and programmed via 3.3V JTAG signals; it does not operate from a 5V supply.

Can this CPLD replace a CY37032-100AXCT in an existing design?

Yes - CY37032VP44-100AXCT is the 3.3V variant of CY37032-100AXCT and shares identical pinout, macrocell count, speed grade (100 MHz), and package (44-pin TQFP). The only differences are VCC requirement (3.3V vs. 5V) and I/O voltage tolerance behavior.

Does this device support boundary scan testing?

Yes - it implements full IEEE 1149.1 JTAG boundary scan with TCK, TMS, TDI, and TDO pins. The boundary scan chain covers all I/Os and internal logic blocks, enabling automated PCB test and in-system diagnostics.

What development tools support this CPLD?

Cypress Warp v6.0+ and third-party tools including Mentor Graphics Precision RTL, Synopsys Synplify, and Aldec Active-HDL fully support the Ultra37000 family. Bitstream generation, timing analysis, and JTAG programming are integrated into these environments.
