Product details
Overview
CY37064P84-125JC from Cypress Semiconductor is a 64-macrocell In-System Reprogrammable (ISR™) CPLD in the Ultra37000 family, operating at 5V with 125 MHz maximum frequency (fMAX) and 6 ns propagation delay (tPD). It features 84-pin PLCC packaging, five dedicated inputs (including four clock pins), and supports both 5V TTL and 3.3V JEDEC-compliant I/O levels via VCCO configuration. Used in legacy PCI bus interface logic, FPGA configuration glue, and industrial control state machines.
For engineers reviewing the CY37064P84-125JC datasheet, CY37064P84-125JC pinout, CY37064P84-125JC application, or CY37064P84-125JC equivalent, key selection criteria include JTAG-based ISR capability, fixed pinout across density upgrades, programmable bus-hold on all I/Os, product-term steering (0–16 per macrocell), and PCI Local Bus electrical compliance.
Technical Context
The CY37064P84-125JC implements a modular architecture with two logic blocks, each containing a 72×87 product term array, intelligent product term allocator, and 16 macrocells (mix of I/O and buried). All signals route through a fully global Programmable Interconnect Matrix (PIM) with no fanout, expander, or PIM-path timing penalties.
It supports four synchronous clocks (CLK0–CLK3) plus one asynchronous product-term clock (PTCLK), with polarity control per logic block. Clocking, set/reset, and output-enable functions are implemented using dedicated product terms with programmable polarity-enabling single-pass OR/AND logic realization without speed penalty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell count | 64 total macrocells across two logic blocks; enables medium-complexity glue logic without FPGA overhead |
| Propagation delay (tPD) | 6 ns worst-case; guarantees deterministic timing for 125 MHz synchronous operation |
| I/O pins | 69 user I/Os in 84-pin PLCC package; includes 5 dedicated inputs (4 clock-capable) |
| Voltage support | 5V core supply with configurable VCCO (3.3V or 5V); enables mixed-voltage board interfacing |
| JTAG interface | IEEE 1149.1-compliant; enables in-system reprogramming without socket removal or timing/pinout changes |
| Bus-hold | Programmable on all I/Os; eliminates external pull-ups and maintains signal state during high-Z transitions |

Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammable (ISR™) | JTAG-based field updates preserve pinout and timing-eliminates PCB respins during logic revisions |
| Intelligent product term allocator | Assigns 0–16 product terms per macrocell dynamically; enables efficient use of 80 local terms without manual routing |
| Fixed pinout migration path | Same 84-pin PLCC footprint used across CY37032/CY37064/CY37128 densities-simplifies hardware scalability |
| PCI Local Bus compliance | Meets electrical and timing requirements for 33 MHz PCI signaling; validated for add-in card control logic |

Applications
| PCI Add-In Card Control Logic | FPGA Configuration Manager |
|---|---|
|
Use Scenario: Managing address decoding, bus arbitration, and interrupt generation for legacy PCI expansion cards in industrial PCs. IC Role / Device Role / Timing Role: Glue logic CPLD handling 33 MHz PCI protocol handshaking, with deterministic 6 ns tPD ensuring setup/hold compliance. Use Value: Replaces discrete 74-series logic with single-device solution; JTAG reprogrammability allows firmware-triggered configuration updates without card removal. |
Use Scenario: Storing and serially loading bitstreams into Xilinx Spartan or Altera Cyclone FPGAs during power-up or field update. IC Role / Device Role / Timing Role: Nonvolatile configuration sequencer with precise clock enable control and CRC validation logic. Use Value: Eliminates external SPI Flash dependency; bus-hold on unused I/Os prevents floating states during FPGA reset sequences. |
| Industrial PLC I/O Expansion | Legacy System Bus Bridge |
|
Use Scenario: Translating between 8-bit parallel microcontroller buses and isolated digital I/O modules in factory automation controllers. IC Role / Device Role / Timing Role: Synchronous state machine implementing handshake protocols with programmable timing margins. Use Value: 5V-tolerant I/Os interface directly to 24V optocoupler inputs; low-power logic block mode reduces thermal load in sealed enclosures. |
Use Scenario: Bridging ISA-to-PCI or Z80-to-ARM bus domains in retro-computing or medical device upgrades. IC Role / Device Role / Timing Role: Asynchronous protocol translator with dual-clock domain crossing (e.g., CLK0 for ISA, CLK1 for PCI). Use Value: Product-term clocking enables event-synchronized transfers; fixed pinout allows drop-in replacement across multiple bridge designs. |
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 |
|---|---|---|---|
| XC9572XL-10VQG44C | 72-macrocell, 3.3V-only, 10 ns tPD, 44-pin VQFP; lacks dedicated clock pins and bus-hold | Requires external pull-ups and level shifters for 5V systems; unsuitable for PCI electrical compliance | Select only for new 3.3V-only designs where JTAG reprogrammability and fixed pinout are secondary priorities |
| ATF1502AS-10JU | 5V ISP CPLD, 44-pin PLCC, 10 ns tPD, 2 dedicated clocks; no product-term steering or PCI compliance | Limited I/O count (32) and clock resources restrict use to simple decode logic-not full bus interface | Consider only for cost-sensitive, low-I/O-count replacements where ISR and timing consistency are not required |
Compared with CY37064P84-125JC, XC9572XL-10VQG44C offers higher density but sacrifices 5V compatibility and PCI readiness, while ATF1502AS-10JU provides lower cost at the expense of I/O scalability and advanced clocking-making CY37064P84-125JC optimal for PCI-adjacent, upgradeable 5V systems.

FAQ
Is CY37064P84-125JC compatible with 3.3V I/O signaling?
Yes. When VCCO pins are connected to 3.3V, outputs meet 3.3V JEDEC standard CMOS levels and remain 5V-tolerant on inputs. Core logic operates at 5V, so 3.3V I/O interfacing requires external level translation only for driving 3.3V-only receivers-not for receiving 5V signals.
Does this device require external configuration memory?
No. CY37064P84-125JC contains on-chip nonvolatile EEPROM for configuration storage. It powers up in configured state without external PROM or Flash; JTAG reprogramming writes directly to internal memory without auxiliary components.
Can the 84-pin PLCC package be replaced with a surface-mount alternative?
Yes. The same CY37064-125 speed grade is offered in 84-pin CLCC and 100-pin TQFP packages. Pinouts are identical across these packages per Cypress documentation, enabling direct migration from through-hole to SMT assembly without logic or PCB redesign.
What development tools support this device?
Cypress Warp v6.0+ and third-party tools including Lattice ispLEVER Classic (with CPLD library import) and older versions of Mentor Graphics Precision RTL provide full synthesis, fitting, and JTAG programming support. Boundary scan testing is IEEE 1149.1-compliant.
