Product details
Overview
CY37032P44-154AXI 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 154 MHz maximum frequency and 6 ns propagation delay. It features four synchronous clocks, five dedicated inputs (including four clock pins), programmable bus-hold on all I/Os, and JTAG-compliant ISR for field reconfiguration without pinout or timing changes. It is PCI-compatible and used in legacy industrial control logic replacement and board-level glue logic consolidation.
For engineers reviewing the CY37032P44-154AXI datasheet, CY37032P44-154AXI pinout, CY37032P44-154AXI application, or CY37032P44-154AXI equivalent, key selection criteria include its fixed 44-pin TQFP footprint across Ultra37000 densities, 5V supply with 3.3V-tolerant I/O, JTAG-based reprogrammability, deterministic timing model with no fanout/expander penalties, and support for both combinatorial and registered I/O configurations.
Technical Context
The CY37032P44-154AXI implements a single logic block architecture with a 72×87 product term array, 80 general-purpose product terms, and 16 macrocells-configured as either I/O or buried macrocells. Its Programmable Interconnect Matrix (PIM) delivers 36 global inputs per logic block with no route-dependent delays, and all timing parameters-including worst-case PIM propagation-are fully specified.
Each macrocell supports D/T/latch register modes with asynchronous set/reset controlled by dedicated product terms, programmable clock polarity per logic block, and independent slew-rate control (fast/slow). Clocking includes four global synchronous clocks (CLK0–CLK3) plus one asynchronous product-term clock (PTCLK), with all five dedicated input pins configurable as combinatorial, registered, double-registered, or latched inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 32 macrocells-provides sufficient logic density for medium-complexity glue logic and state-machine implementation without requiring multiple devices. |
| Max Frequency (fMAX) | 154 MHz-enables reliable operation in high-speed digital control loops and data-path synchronization up to 154 million state transitions per second. |
| Propagation Delay (tPD) | 6 ns-guarantees predictable timing closure in 5V systems with minimal skew between I/O paths and internal logic. |
| I/O Pins | 32 user I/O pins-matches the 44-pin TQFP package's 37 usable I/O count (excluding power/ground/JTAG pins), supporting full parallel bus interfacing. |
| Supply Voltage | 5.0 V ± 5%-requires stable 5V rail; VCCO pins support 3.3V or 5V I/O levels, enabling mixed-voltage board interfacing with 5V-tolerant inputs. |
| JTAG Interface | IEEE 1149.1-compliant-enables in-system reprogramming, boundary-scan testing, and design iteration without device removal or socketing. |
| PCI Compatibility | Fully compliant with PCI Local Bus Specification Rev. 2.2 electrical and timing requirements-validates use in add-in cards and host-bridge logic without external level-shifting. |
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 | JTAG Test Clock | Synchronizes JTAG instruction and data shifts; must be driven externally during programming and boundary-scan operations. |
| TMS | JTAG Test Mode Select | Controls JTAG state machine progression; sampled on rising TCK edge to determine next test mode. |
| TDI | JTAG Test Data Input | Serial input for configuration bitstream and test data; connects to upstream JTAG device or programmer output. |
| TDO | JTAG Test Data Output | Serial output for readback and boundary-scan response; daisy-chained to downstream JTAG device input. |
| VCC | Main Power Supply | 5V core supply for logic and macrocell operation; requires local 0.1 µF ceramic decoupling adjacent to pin. |
| GND | Ground Reference | Digital ground return for all internal logic and I/O; multiple GND pins ensure low-impedance return path. |
| I/O0–I/O31 | Configurable Bidirectional I/O | Supports input, output, or bidirectional operation with programmable bus-hold, slew rate, and drive strength. |
| CLK0–CLK3 | Dedicated Clock Inputs | Four global synchronous clocks; each configurable for rising/falling-edge triggering per logic block. |
| PTCLK | Product Term Clock Input | Asynchronous clock derived from local product term equation; enables event-driven state transitions independent of global clocks. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | Enables field firmware updates and logic fixes via JTAG without changing PCB layout or timing constraints-critical for long-lifecycle industrial deployments. |
| Fixed Pinout Across Densities | Same 44-pin TQFP footprint used for CY37032, CY37064, and CY37128-allows hardware design reuse and seamless migration to higher-density CPLDs. |
| No Fanout/Expander Timing Penalties | Timing model eliminates delay dependencies on signal fanout or product-term expansion-simplifies static timing analysis and guarantees worst-case performance. |
| Programmable Bus-Hold on All I/Os | Eliminates need for external pull-up resistors on unused or tri-stated pins, reducing BOM cost and board space while suppressing floating-input noise in bus applications. |
| Flexible Macrocell Configuration | Each of 16 macrocells per logic block supports independent register mode (D/T/latch), clock source (CLK0–CLK3 or PTCLK), and polarity control-maximizing logic utilization efficiency. |
Applications
| Industrial PLC I/O Expansion | Legacy System Glue Logic Replacement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based glue logic and control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMD XC9536XL-10VQG44C | 36 macrocells, 3.3V-only supply, 10 ns tPD, non-JTAG ISP (uses proprietary Xilinx-style JTAG), smaller PIM routing resources. | Limited to 3.3V systems; lacks 5V tolerance and PCI-compliant drive strength; requires different programming hardware. | Select only if migrating to 3.3V-only infrastructure and accepting reduced I/O drive capability. |
| Lattice ISPLSI 2032A-135LQ44 | 32 macrocells, 3.3V supply, 13.5 ns tPD, IEEE 1149.1 JTAG, but no dedicated clock pins-clocks share general I/O. | Lower max frequency (74 MHz vs. 154 MHz); no fixed clock pin assignment reduces timing predictability in synchronous designs. | Acceptable for non-critical timing applications where JTAG reprogrammability is primary requirement and speed margin is not constrained. |
Compared with XC9536XL-10VQG44C and ISPLSI 2032A-135LQ44, CY37032P44-154AXI uniquely combines 5V operation with 3.3V-tolerant I/O, PCI compliance, four dedicated clock pins, and deterministic 6 ns timing-making it the only choice for maintaining legacy 5V system interoperability while retaining field-upgrade capability.

FAQ
Is CY37032P44-154AXI compatible with 3.3V I/O buses?
Yes. The device operates from a 5V VCC supply but supports 3.3V I/O levels when VCCO pins are connected to 3.3V. All I/Os are 5V-tolerant, allowing direct connection to 3.3V buses without level shifters while meeting JEDEC-standard CMOS output specifications.
Can CY37032P44-154AXI replace older 22V10 PALs in existing designs?
Yes-its architecture extends the 22V10 paradigm to higher density with full backward compatibility in logic modeling. Pin-compatible migration is supported via the same 44-pin TQFP footprint and identical JTAG programming flow, though HDL recompilation is required due to expanded resource allocation.
Does this device require external configuration memory?
No. CY37032P44-154AXI contains on-chip nonvolatile EEPROM for configuration storage. It powers up in configured state without external PROM or FPGA-style configuration controllers-reducing system complexity and boot time.
What development tools support CY37032P44-154AXI?
Cypress Warp v6.0+ and third-party tools including Lattice ispLEVER Classic (with Cypress library import) and Synplicity Synplify Pro support synthesis, fitting, and JTAG programming. Boundary-scan testing is enabled via standard IEEE 1149.1 test vectors.
