Product details
Overview
CY37064P100-125AC from Cypress Semiconductor is a 64-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, operating at 5V with 100-pin TQFP package and 125 MHz maximum frequency (tPD = 12.5 ns). It features four synchronous clocks, programmable bus-hold on all I/Os, and JTAG-compliant ISR for field reconfiguration without pinout or timing changes. Used in legacy PCI interface logic, system boot configuration, and FPGA companion control.
For engineers reviewing the CY37064P100-125AC datasheet, CY37064P100-125AC pinout, CY37064P100-125AC application, or CY37064P100-125AC equivalent, key selection criteria include macrocell count, I/O pin count (69), tPD timing bin (125), VCCO voltage flexibility (5V/3.3V I/O support), and JTAG boundary-scan compliance for testability.
Technical Context
The CY37064P100-125AC implements a modular architecture with two logic blocks, each containing 32 macrocells, a 72×87 product term array, and an intelligent product term allocator supporting 0–16 product terms per macrocell. All inputs route through a fully global Programmable Interconnect Matrix (PIM) with no fanout, expander, or PIM-induced delay penalties.
It supports flexible clocking via four dedicated synchronous clocks (CLK0–CLK3) and one asynchronous product term clock (PTCLK), with polarity control per logic block. Bus-hold and slew-rate control are programmable per I/O, and all I/Os are 5V-tolerant when VCCO = 3.3V - critical for mixed-voltage board interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 64 total, distributed across two logic blocks - enables medium-complexity glue logic without FPGA overhead. |
| Maximum Frequency (fMAX) | 125 MHz - guarantees deterministic timing for PCI Local Bus and control-plane logic up to 33 MHz system clocks. |
| Propagation Delay (tPD) | 12.5 ns - fixed worst-case path delay, independent of fanout or product term sharing due to PIM architecture. |
| I/O Pins | 69 user-programmable I/Os in 100-pin TQFP - supports dense peripheral bridging with fixed pinout across speed bins. |
| VCCO Support | Configurable 5V or 3.3V output levels - allows direct interfacing to both TTL and JEDEC-compliant CMOS buses without level shifters. |
| JTAG Interface | IEEE 1149.1-compliant - enables in-system reprogramming, boundary-scan testing, and design iteration without hardware modification. |
| Power Supply (VCC) | 5.0V ± 5% - requires single 5V rail; VCCO pins independently set for I/O voltage level selection. |
Pinout & Package
Packaged in a 100-lead Thin Quad Flat Package (TQFP), the CY37064P100-125AC uses a standard 0.5 mm pitch, 14 × 14 mm body size, with exposed thermal pad (non-electrical) and lead-free finish compliant with RoHS Directive 2011/65/EU.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TCK, TMS, TDI, TDO | JTAG Test Access Port | Enable boundary-scan testing and serial ISP programming; TDO is open-drain, others are CMOS-compatible inputs. |
| CLK0–CLK3 | Dedicated Clock Inputs | Four globally distributed synchronous clocks; each configurable for rising/falling edge triggering per logic block. |
| OE[0:3] | Output Enable Controls | Four programmable OE product terms - each controls up to eight macrocells, enabling fine-grained tri-state management. |
| VCCO[0:3] | I/O Power Supply | Four independent VCCO pins - grouped to supply specific I/O banks; setting to 3.3V enables 5V-tolerant outputs. |
| GND, VCC | Power Distribution | 12 GND and 4 VCC pins - ensure low-noise power delivery and reduce simultaneous switching noise in high-speed logic. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | JTAG-based field updates preserve pinout and timing - eliminates PCB respins during firmware-driven logic revisions. |
| Programmable Bus-Hold | Weak latch on every I/O - maintains last valid state during high-Z, eliminating external pull-ups in bus-hold applications like address/data latching. |
| Flexible Product Term Allocation | 0–16 product terms assignable per macrocell - supports heterogeneous logic depth (e.g., wide decoders + narrow state machines) in same device. |
| Programmable Slew Rate | Fast/slow edge selection per output - reduces EMI in noise-sensitive environments while retaining full-speed capability where needed. |
| Dedicated Input/Clock Pins | Five dedicated inputs including four clock-capable pins - simplifies clock domain crossing and eliminates routing congestion for timing-critical paths. |
Applications

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 macrocells, 44-pin VQFP, 3.3V-only supply, 10 ns tPD - lacks VCCO flexibility and 5V tolerance. | Requires level-shifting for 5V legacy buses; unsuitable for mixed-voltage PCI designs without external translators. | Select only if system operates exclusively at 3.3V and board space constraints favor smaller package. |
| ATF1504AS-10AU100 | 128 macrocells, 100-pin TQFP, 3.3V supply, 10 ns tPD - higher density but no 5V operation or VCCO-selectable I/O. | Cannot replace CY37064P100-125AC in 5V systems without redesign; JTAG implementation differs in boundary-scan register mapping. | Prefer for new 3.3V-only designs needing >64 macrocells and faster timing, but verify JTAG toolchain compatibility. |
Compared with XC9572XL-10VQG44C and ATF1504AS-10AU100, the CY37064P100-125AC uniquely supports dual-voltage I/O via VCCO pins and retains full 5V system compatibility - making it irreplaceable in legacy PCI and mixed-rail industrial backplanes where voltage translation adds cost and failure modes.

FAQ
Is CY37064P100-125AC 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 remain 5V-tolerant in this mode, meeting JEDEC 3.3V CMOS specifications. This allows seamless interfacing with both 3.3V and 5V peripherals without external level shifters.
Does CY37064P100-125AC require external configuration memory?
No. It is electrically erasable and nonvolatile - configuration data is stored internally in EEPROM cells. After power-up, the device operates immediately without relying on external PROM or flash memory, reducing BOM count and boot latency.
Can the JTAG interface be used for both programming and debugging?
Yes. The IEEE 1149.1-compliant JTAG port supports boundary-scan testing (BST), in-system reprogramming (ISP), and real-time visibility into internal logic states during emulation - enabling hardware validation and field firmware updates without physical access to configuration pins.
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. This allocation is dynamic and software-determined during place-and-route - no hardware limitation prevents full utilization of all 80 local product terms across the 32-macrocell logic block.
