Infineon Technologies CY37032VP44-100JXI

Overview

CY37032VP44-100JXI from Cypress Semiconductor is a 3.3V In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, featuring 32 macrocells, 32 I/O pins, 5 dedicated inputs (including 4 clock inputs), and a 100 MHz maximum operating frequency (f_MAX). It uses a JTAG-compliant serial interface for reconfiguration and supports programmable bus-hold, slew-rate control, and product-term clocking. It is deployed in legacy industrial control logic replacement and PCI-compliant board-level glue logic.

For engineers reviewing the CY37032VP44-100JXI datasheet, CY37032VP44-100JXI pinout, CY37032VP44-100JXI application, or CY37032VP44-100JXI equivalent, key selection criteria include its 3.3V V_CC/V_CCO operation, 44-pin TQFP package with fixed pinout across density variants, ISR capability without timing/pinout impact, and support for both synchronous (CLK0–CLK3) and asynchronous (PTCLK) clocking modes.

Technical Context

The CY37032VP44-100JXI implements a single logic block architecture with a 72 × 87 product term array, delivering up to 80 general-purpose product terms plus dedicated set/reset, OE, and product-term clock terms. Its Programmable Interconnect Matrix (PIM) provides 36 global inputs per logic block and eliminates route-dependent delays - all PIM propagation is fully characterized in t_PD = 10 ns and f_MAX = 100 MHz specs.

Each of its 16 macrocells supports D/T/latch configuration with asynchronous set/reset, polarity-controlled clocks, and independent output enable selection. All I/Os feature programmable bus-hold and slew-rate control (fast/slow), and the device accepts 3.3V supply while maintaining 5V-tolerant I/O levels - critical for mixed-voltage PCI Local Bus interfacing.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a U.S.-based semiconductor company specializing in programmable logic, memory, and USB/USB-C solutions, founded in 1982 and headquartered in San Jose, California.

The Ultra37000 CPLD family was designed to deliver high-density, pin-compatible, and timing-predictable programmable logic for industrial control, communications infrastructure, and legacy system modernization - emphasizing ISR, low-power operation, and mixed-voltage interoperability.

FAQ

Is CY37032VP44-100JXI compatible with 5V PCI bus signaling?

Yes. Although it operates at 3.3V V_CC, its I/Os are 5V-tolerant and meet PCI Local Bus electrical specifications when V_CCO = 3.3V. Input thresholds satisfy PCI VIH ≥ 2.0V, and output drive strength complies with PCI sink/source current requirements - no level-shifting components are needed.

Can the device retain configuration after power loss?

Yes. CY37032VP44-100JXI uses electrically erasable (EEPROM-based) nonvolatile configuration memory. Configuration is retained indefinitely without power, and no external configuration PROM is required - unlike SRAM-based FPGAs.

What development tools support this device?

Cypress Warp v6.2 and later, along with third-party tools including Mentor Graphics Precision RTL, Synopsys Synplify, and Xilinx ISE (via CPLD import flow), fully support CY37032VP44-100JXI synthesis, place-and-route, and JTAG programming using standard IEEE 1149.1 adapters.

Does the 44-pin TQFP package support thermal rework?

Yes. The 44-pin TQFP (JEDEC MO-148AA) has gull-wing leads with 0.8 mm pitch and is qualified for standard reflow profiles (J-STD-020). Cypress specifies peak reflow temperature of 260°C for 10 seconds; board-level thermal profiling is recommended to avoid solder joint voiding.
