Product details
Overview
CY37032P44-125AXC from Cypress Semiconductor is a 32-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in a 44-pin TQFP package, operating at 5V with 125 MHz maximum frequency (tPD = 12.5 ns), PCI-compatible I/O, and JTAG-based reconfiguration. It features four synchronous clocks, programmable bus-hold on all I/Os, and supports both combinatorial and registered logic functions in embedded control and glue-logic applications.
For engineers reviewing the CY37032P44-125AXC datasheet, CY37032P44-125AXC pinout, CY37032P44-125AXC application, or CY37032P44-125AXC equivalent, key selection criteria include macrocell count, ISR capability, PCI compliance, 44-pin TQFP footprint, and 125 MHz fMAX timing performance for legacy system upgrades and industrial control logic replacement.
Technical Context
The CY37032P44-125AXC implements the Ultra37000 architecture with one logic block containing a 72×87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells-configured as I/O or buried registers. Its Programmable Interconnect Matrix (PIM) delivers fixed, route-independent timing by routing all signals-including feedback and dedicated inputs-through a global 36-input matrix.
It supports flexible clocking via four global synchronous clocks (CLK0–CLK3) plus a product-term clock (PTCLK), with polarity control per logic block; all five dedicated input pins include clock-capable terminals, and bus-hold is enabled per I/O pin without external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 32 - provides sufficient logic density for medium-complexity glue logic and state-machine implementation |
| Max Frequency (fMAX) | 125 MHz - guarantees synchronous operation up to 8 ns clock period in critical paths |
| Propagation Delay (tPD) | 12.5 ns - worst-case path delay from input to registered output, independent of routing congestion |
| I/O Pins | 37 - actual usable I/O count in 44-pin TQFP package, including 5 dedicated inputs (4 clock-capable) |
| Supply Voltage | 5V VCC - requires 5V core supply; VCCO configurable for 3.3V or 5V I/O levels with 5V-tolerant inputs |
| JTAG Interface | IEEE 1149.1 compliant - enables in-system reprogramming and boundary-scan testing without device removal |
| PCI Compatibility | Fully compliant - meets electrical and timing requirements of PCI Local Bus Specification Rev. 2.2 |
Pinout & Package
Package: 44-pin 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 boundary-scan interface | Enable in-system programming and test access without interrupting system operation |
| CLK0–CLK3 | Dedicated synchronous clock inputs | Provide four independent clock domains per logic block; each supports programmable polarity |
| OE[0:3] | Output enable control inputs | Configure group-level tristate control for I/O macrocells using local product terms |
| I/O[0:36] | Programmable bidirectional I/O pins | Support bus-hold, slew-rate control (fast/slow), and 5V-tolerant 3.3V/5V I/O switching |
| GND, VCC, VCCO | Power and ground terminals | VCC = 5V core supply; VCCO sets I/O voltage level (3.3V or 5V); separate VCCO pins per I/O bank |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | JTAG-based field updates preserve pinout and timing across design iterations, eliminating board respins |
| Intelligent Product Term Allocator | Dynamically assigns 0–16 product terms per macrocell and enables sharing across groups of four macrocells without speed penalty |
| Fixed-Timing Architecture | No fanout, expander, or PIM-routing delays - all timing parameters are worst-case guaranteed and route-independent |
| Programmable Bus-Hold | On-chip weak latch on every I/O eliminates need for external pull-ups and prevents floating-bus noise during high-Z states |
| Slew Rate Control | Per-output fast/slow edge selection reduces EMI in noise-sensitive environments while maintaining speed where needed |
Applications
| Industrial PLC I/O Expansion | Legacy PCI Add-in Card Logic |
|---|---|
Use Scenario: Replacing discrete TTL logic in programmable logic controller backplanes to consolidate address decoding, interrupt arbitration, and status multiplexing. IC Role / Device Role / Timing Role: Glue logic CPLD implementing synchronous register-to-register transfers and asynchronous control signal generation with deterministic 12.5 ns propagation. Use Value: Reduces component count by >70% versus 74-series, maintains compatibility with existing 5V PCI slots, and enables firmware-upgradable control logic. | Use Scenario: Serving as configuration and interface logic on PCI-based data acquisition cards requiring precise timing alignment between ADC sampling and host DMA handshaking. IC Role / Device Role / Timing Role: PCI-compliant I/O buffer and protocol translator managing DEVSEL#, FRAME#, and IRDY# with sub-8 ns setup/hold margins. Use Value: Meets PCI Rev. 2.2 electrical specs without level-shifters; JTAG reprogrammability allows late-stage timing tuning post-layout. |
| Automotive Body Control Module | Test Equipment Signal Conditioning |
Use Scenario: Managing door lock actuation sequencing, window motor direction control, and mirror position latching in 12V automotive systems with 5V logic rails. IC Role / Device Role / Timing Role: Combinatorial and registered logic engine handling multi-step safety interlocks and debounce filtering with bus-hold preventing spurious transitions on unconnected pins. Use Value: Eliminates need for external RC filters and pull resistors; 5V-tolerant I/O interfaces directly to switch sensors and relay drivers. | Use Scenario: Adapting mixed-voltage digital signals (3.3V FPGA outputs, 5V microcontroller inputs) in automated test equipment front-ends. IC Role / Device Role / Timing Role: Level-translating and protocol-synchronizing interface CPLD with independent clock domains for source and sink sides. Use Value: Enables seamless integration of heterogeneous logic families; programmable slew rate suppresses ground bounce during parallel bus toggling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based glue logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC9536XL-10VQ44C | 36 macrocells, 3.3V-only supply, 10 ns tPD, Xilinx CoolRunner-II architecture with lower static current | Lacks PCI compliance and 5V-tolerant I/O; requires level-shifting in mixed-voltage systems | Preferred for battery-powered or low-power portable test gear where 5V tolerance is unnecessary |
| ATF1502AS-10QU44 | 32 macrocells, 3.3V supply, 10 ns tPD, Atmel (Microchip) ISP CPLD with JTAG and IEEE 1149.1 support | No bus-hold; requires external pull-ups; not certified for PCI electrical compliance | Suitable for cost-sensitive industrial controllers where PCI slot insertion is not required |
Compared with CY37032P44-125AXC, the XC9536XL offers faster timing but sacrifices 5V system interoperability, while the ATF1502AS reduces BOM cost but increases board-level design effort due to missing bus-hold and PCI certification.

FAQ
Is CY37032P44-125AXC compatible with 3.3V I/O signaling?
Yes - the device supports 3.3V I/O levels when VCCO pins are connected to 3.3V; all I/Os are 5V-tolerant regardless of VCCO setting, enabling safe interfacing with both 3.3V and 5V logic families without level shifters.
Does this device require external configuration memory?
No - CY37032P44-125AXC contains on-chip nonvolatile EEPROM for configuration storage; it powers up fully operational without external PROM or FPGA-style configuration loading sequences.
Can the JTAG interface be used for both programming and debugging?
Yes - the IEEE 1149.1 JTAG port supports boundary-scan testing (BST), in-system programming (ISP), and real-time visibility into internal logic states via debug probes compatible with Cypress Warp software and third-party tools.
What is the maximum number of product terms usable per macrocell?
Up to 16 product terms can be allocated to any single macrocell via the intelligent product term allocator; unused macrocells may receive zero terms, and shared terms across macrocell groups do not reduce per-macrocell term count.
