Product details
Overview
CY37064P44-154JXI from Cypress Semiconductor is a 64-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, programmable bus-hold on all I/Os, and JTAG-compliant reconfiguration. Used in legacy PCI interface logic, board-level glue logic, and FPGA configuration support circuits.
For engineers reviewing the CY37064P44-154JXI datasheet, CY37064P44-154JXI pinout, CY37064P44-154JXI application, or CY37064P44-154JXI equivalent, key selection criteria include macrocell count, I/O pin count (37 usable), tPD timing bin (154 speed grade), VCCO voltage flexibility (5V/3.3V I/O), and JTAG-based ISR capability for field updates without pinout or timing impact.
Technical Context
The CY37064P44-154JXI implements the Ultra37000 architecture with two logic blocks, each containing a 72×87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells. All inputs route through a fully global Programmable Interconnect Matrix (PIM) with no route-dependent delays.
It supports four dedicated synchronous clocks (CLK0–CLK3) plus one asynchronous product-term clock (PTCLK), programmable slew rate per output, and configurable macrocell modes (combinatorial, D/T/latch, async set/reset). Bus-hold is enabled per I/O pin via configuration bit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 64 total - provides combinational and registered logic capacity equivalent to ~1,500 usable gates |
| Maximum Frequency (fMAX) | 154 MHz - defines highest reliable synchronous operation speed under worst-case conditions |
| Propagation Delay (tPD) | 6 ns - worst-case input-to-output delay across PIM and logic block, independent of fanout or routing |
| I/O Pins | 37 user-programmable I/Os in 44-pin TQFP - includes 5 dedicated inputs (4 clock-capable) |
| Supply Voltage | 5V VCC with 3.3V/5V-tolerant VCCO - enables mixed-voltage board interfacing without level shifters |
| JTAG Interface | IEEE 1149.1-compliant - enables in-system reprogramming, boundary scan testing, and debug visibility |
| Bus-Hold Enable | Per-pin programmable - eliminates external pull-ups on unused or floating I/Os during prototyping or hot-swap |
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 | Drives JTAG state machine; requires clean 5V CMOS clock signal for ISP and boundary scan |
| TMS | JTAG Test Mode Select | Controls JTAG instruction register state transitions during programming or test |
| TDI | JTAG Test Data Input | Serial input for configuration bitstream, instructions, or test data during ISP |
| TDO | JTAG Test Data Output | Serial output for readback, verification, or boundary scan response |
| CLK0–CLK3 | Dedicated Synchronous Clock Inputs | Four globally distributed clocks; each configurable for rising/falling edge triggering per logic block |
| VCCO | I/O Power Supply | Set to 3.3V or 5V to define output voltage levels and input tolerance; decoupling required per pin group |
| GND | Ground Reference | Multiple dedicated pins (pins 11, 22, 33, 44) - must be individually decoupled for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | Enables full logic reconfiguration in-circuit via JTAG without removing device or changing PCB layout |
| Fixed Pinout Across Density Migration | Same 44-pin TQFP footprint used for CY37032/CY37064 - allows hardware reuse when scaling logic complexity |
| Programmable Slew Rate Control | Per-output fast/slow edge selection reduces EMI in FCC-compliant designs or maximizes timing margin in high-speed paths |
| Intelligent Product Term Allocator | Dynamically assigns 0–16 product terms per macrocell and shares terms across local groups - eliminates manual resource allocation |
| 5V-Tolerant 3.3V I/O Operation | VCCO = 3.3V yields JEDEC-compliant outputs while accepting 5V inputs - simplifies mixed-voltage interconnect |
Applications
| PCI Bus Interface Logic | Legacy System Glue Logic |
|---|---|
Use Scenario: Implementing address decoding, bus arbitration, and control signal generation between PCI slot and custom ASIC/FPGA. IC Role / Device Role / Timing Role: CPLD acts as synchronous protocol translator and timing bridge, handling PCI clock domain crossing and setup/hold compliance. Use Value: Fixed 6 ns tPD ensures deterministic timing closure across all PCI clock phases; JTAG reprogrammability supports late-stage protocol tweaks without board respin. |
Use Scenario: Replacing discrete TTL logic (74-series) in industrial control backplanes with aging microcontrollers. IC Role / Device Role / Timing Role: Configurable combinatorial and registered logic block providing enable gating, state sequencing, and interrupt prioritization. Use Value: 37 I/Os and 64 macrocells consolidate >20 SMT discretes; bus-hold eliminates need for external pull-ups on uncommitted pins during field upgrades. |
| FPGA Configuration Support | Board-Level Power Sequencing |
Use Scenario: Managing startup sequence and status monitoring for Xilinx Spartan or Altera Cyclone FPGAs on embedded carrier boards. IC Role / Device Role / Timing Role: CPLD generates reset deassertion timing, configures FPGA mode pins, and validates configuration completion via INIT_B handshake. Use Value: Four dedicated clocks allow independent timing control of FPGA power rails, configuration clocks, and status polling loops. |
Use Scenario: Coordinating multi-rail power-up order (12V → 5V → 3.3V → 1.8V) and fault monitoring in telecom line cards. IC Role / Device Role / Timing Role: State-machine-based sequencer with analog comparator inputs (via external resistive dividers) and programmable delay timers. Use Value: Programmable slew rate minimizes ground bounce during simultaneous rail enable; JTAG access enables runtime adjustment of timing thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC9572XL-10VQG44C | 72 macrocells, 3.3V-only supply, 10 ns tPD, 125 MHz fMAX; no VCCO voltage flexibility | Lacks 5V-tolerant I/O and dual-voltage operation - requires level shifters in mixed-voltage systems | Select when design uses only 3.3V rails and requires higher macrocell density than CY37064 |
| ATF1504AS-10QU44 | 64 macrocells, 3.3V supply, 10 ns tPD, JTAG ISP; no bus-hold or programmable slew rate | No per-pin bus-hold - external pull-ups needed for floating I/Os; no EMI control via edge rate tuning | Select for cost-sensitive, single-voltage applications where JTAG reprogrammability is primary requirement |
Compared with XC9572XL-10VQG44C and ATF1504AS-10QU44, CY37064P44-154JXI uniquely supports 5V/3.3V I/O interoperability, per-pin bus-hold, and programmable slew control - critical for legacy system integration and EMI-constrained environments.

FAQ
Is CY37064P44-154JXI compatible with 3.3V-only systems?
Yes, but with constraints: VCCO must be tied to 3.3V to meet JEDEC 3.3V output levels, and VCC remains at 5V. The I/Os are 5V-tolerant, enabling safe connection to 5V signals. However, internal logic operates at 5V, so true 3.3V-only operation (like CY37064V variants) is not supported.
Can CY37064P44-154JXI replace older CY37064-154JC models?
Yes - the 'JXI' suffix denotes extended industrial temperature range (–40°C to +85°C) and lead-free packaging, while maintaining identical logic architecture, pinout, timing, and JTAG interface as the 'JC' version. No firmware or PCB changes are required for drop-in replacement.
What development tools support CY37064P44-154JXI programming?
Cypress Warp v6.0+ and third-party tools including Lattice ispLEVER Classic (with Cypress library add-on) and older versions of Mentor Graphics Leonardo Spectrum support this device. JTAG programming is fully compliant with IEEE 1149.1, enabling use with standard boundary-scan programmers like Xilinx Impact or Teradyne J750.
Does CY37064P44-154JXI require external configuration memory?
No - it contains on-chip nonvolatile EEPROM for configuration storage. After power-up, it self-configures automatically. External memory is only needed if using parallel programming mode (not JTAG), which is rarely used; JTAG programming writes directly to internal EEPROM.
