Product details
Overview
CY37032VP44-100AC 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/O pins in a 44-lead TQFP package. It supports 3.3V JEDEC CMOS output levels with 5V-tolerant I/Os, 10 ns maximum propagation delay (tPD), and 100 MHz maximum operating frequency (fMAX). It is used in legacy industrial control logic replacement and PCI-compliant interface glue logic.
For engineers reviewing the CY37032VP44-100AC datasheet, CY37032VP44-100AC pinout, CY37032VP44-100AC application, or CY37032VP44-100AC equivalent, key selection criteria include JTAG-based ISR capability, programmable bus-hold on all I/Os, product-term-steerable macrocell architecture, and compatibility with Warp® and third-party synthesis tools for rapid design iteration without pinout or timing changes.
Technical Context
The CY37032VP44-100AC implements a single logic block with a 72 × 87 product term array delivering up to 16 product terms per macrocell, configurable as combinatorial, D/T/latch, or registered outputs. Its Programmable Interconnect Matrix (PIM) routes 36 global signals-including macrocell feedbacks and all I/O pins-to the logic block with zero route-dependent timing penalties.
It supports four synchronous clocks (CLK0–CLK3) plus one asynchronous product-term clock (PTCLK), all with programmable polarity. Clocking, set/reset, and output-enable functions are controlled via dedicated product terms with polarity-selectable OR/AND logic realization-enabling full logic expression implementation in a single pass through the array.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 32 - provides combinational and registered logic capacity for small-to-medium state machines and glue logic |
| Max Propagation Delay (tPD) | 10 ns - guarantees deterministic timing for 100 MHz system clock domains without fanout or routing penalties |
| I/O Pins | 37 - fixed count in 44-lead TQFP; includes 5 dedicated inputs (4 clock-capable) and bus-hold enabled on all |
| Supply Voltage | 3.3 V ± 0.3 V - requires 3.3V VCC and 3.3V VCCO; enables 3.3V JEDEC-compliant outputs with 5V-tolerant inputs |
| JTAG Interface | IEEE 1149.1 compliant - enables in-system reprogramming and boundary-scan testing without device removal |
| Logic Block Count | 1 - contains 16 macrocells, 72×87 product term array, intelligent allocator, and PIM input distribution |
| Slew Rate Control | Programmable fast/slow per output - reduces EMI in noise-sensitive environments or maximizes edge speed for timing-critical paths |
Pinout & Package
Package: 44-lead Thin Quad Flat Package (TQFP), 10 mm × 10 mm, 0.8 mm pitch, RoHS-compliant lead-free option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TCK, TMS, TDI, TDO | JTAG Test Access Port | Enable IEEE 1149.1 boundary scan and in-system reprogramming; no external programming hardware required |
| CLK0–CLK3 | Dedicated Synchronous Clock Inputs | Four globally distributed clocks with programmable polarity; each selectable per macrocell for mixed-edge logic |
| PTCLK | Asynchronous Product-Term Clock | Enables event-driven clocking derived from internal logic equations-not tied to physical pin |
| I/O[0]–I/O[36] | Configurable Bidirectional I/O | All support programmable bus-hold, slew rate, pull-up/down disable, and input register/latch modes |
| VCC, VCCO, GND | Power and Ground | VCC = 3.3V core supply; VCCO = 3.3V I/O supply (no 5V option in 'V' suffix devices); separate ground pins reduce noise coupling |
Key Features

FAQ
Is CY37032VP44-100AC compatible with 5V I/O buses?
No. The 'V' suffix denotes a 3.3V-only device: VCC and VCCO must both be 3.3V. While its I/Os are 5V-tolerant (inputs accept up to 5.5V), it cannot drive 5V TTL levels. For true 5V operation, use the non-V variant CY37032-100AC, which requires 5V VCC and supports 5V or 3.3V VCCO selection.
Does this device require external pull-up resistors on unused I/O pins?
No. All I/O pins feature user-programmable bus-hold circuitry, which actively maintains the last driven logic state when the pin is tri-stated. This eliminates the need for external pull-up or pull-down resistors-reducing component count and improving noise immunity in unconnected or intermittently driven pins.
Can the CY37032VP44-100AC be programmed in-system after soldering to the PCB?
Yes. It supports full IEEE 1149.1 JTAG in-system reprogramming (ISR™) via TCK, TMS, TDI, and TDO pins. No socket or programming fixture is required-firmware updates, logic fixes, or configuration changes can be performed directly on the assembled board using standard JTAG debuggers or Cypress-provided tools.
What development tools support this CPLD?
Cypress Warp® software (legacy) and third-party tools including Lattice Diamond (via .jed export), Mentor Graphics Precision RTL, and Synopsys Synplify Pro fully support the Ultra37000 family. Pin assignment, fitting, and timing analysis are automated; no manual routing or delay calculation is needed due to the architecture's uniform timing model.
