Product details
Overview
CY37512VP256-66BGC from Cypress Semiconductor is a 512-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, operating at 3.3V with 66 ns maximum propagation delay (tPD) and 83 MHz maximum frequency (fMAX). It features 264 I/O pins, five dedicated inputs (including four clock inputs), and JTAG-compliant reprogramming capability. It is used in PCI-compliant interface logic, legacy bus bridging, and system control state machines where pinout stability across design iterations is critical.
For engineers reviewing the CY37512VP256-66BGC datasheet, CY37512VP256-66BGC pinout, CY37512VP256-66BGC application, or CY37512VP256-66BGC equivalent, key selection criteria include its 3.3V operation with 5V-tolerant I/Os, programmable slew rate per output, bus-hold on all I/Os, product-term steering/sharing architecture, and fixed-pinout migration path across Ultra37000 densities.
Technical Context
The CY37512VP256-66BGC implements a multi-block CPLD architecture with a global Programmable Interconnect Matrix (PIM) routing all I/O and macrocell feedback signals to 36-input logic blocks. Each block contains a 72×87 product term array, intelligent allocator for 0–16 product terms per macrocell, and 16 macrocells-some I/O, some buried-with configurable D/T/latch registers.
It supports four synchronous clocks (CLK0–CLK3) plus one asynchronous product-term clock (PTCLK), programmable polarity per clock, and dual-mode logic blocks (high-speed or low-power). All I/Os feature programmable bus-hold and slew-rate control, and the device complies electrically with PCI Local Bus specification requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 512 - provides scalable logic density for complex glue logic and state-machine implementation |
| I/O Pins | 264 - supports high-pin-count parallel bus interfaces including PCI and memory-mapped peripherals |
| Propagation Delay (tPD) | 66 ns - guarantees timing closure for 83 MHz synchronous operation without fanout or expander penalties |
| Supply Voltage | 3.3V ±0.3V - enables direct interfacing with 3.3V JEDEC CMOS systems while maintaining 5V tolerance on I/Os |
| Dedicated Inputs | 5 - includes four clock inputs and one general-purpose input, enabling flexible clock domain management |
| JTAG Interface | IEEE 1149.1-compliant - enables in-system reprogramming without board removal or socketing |
| Bus-Hold | Programmable per I/O - eliminates need for external pull-ups during prototyping or floating-bus conditions |
Pinout & Package
This device is packaged in a 256-pin Fine-Pitch Ball Grid Array (FBGA) with 1.0 mm ball pitch, RoHS-compliant and lead-free. Pinout follows the standard Ultra37000 256-pin FBGA mapping (Package Code: BGC), supporting consistent layout reuse across 3.3V and 5V variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TCK, TMS, TDI, TDO | JTAG boundary-scan and ISR control | Enable in-system programming and test without disrupting system operation |
| CLK0–CLK3 | Dedicated synchronous clock inputs | Provide independent clock domains per logic block; polarity programmable per block |
| VCC, VCCO, GND | Power and reference | VCCO = 3.3V sets I/O voltage level; all I/Os are 5V-tolerant regardless of VCCO setting |
| I/O[0]–I/O[263] | Configurable bidirectional I/O | Each supports bus-hold, slew-rate control, and register/combinatorial modes |
| PTCLK | Asynchronous product-term clock | Enables event-driven logic updates independent of global clocks |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | JTAG-based field updates preserve pinout and timing - eliminates redesign risk during firmware or logic iteration |
| Intelligent Product Term Allocator | Dynamically assigns 0–16 product terms per macrocell and shares terms across groups of four - maximizes logic utilization without speed penalty |
| Fixed Pinout Migration | Identical 256-pin FBGA footprint across all Ultra37000 densities - enables hardware reuse from CY37256V to CY37512V |
| PCI Electrical Compliance | Meets PCI Local Bus Specification voltage thresholds and timing - certified for use in add-in cards and host-bridge logic |
| Programmable Slew Rate | Per-output fast/slow edge selection - balances EMI reduction and timing margin in mixed-signal PCBs |
Applications
| PCI Add-In Card Control Logic | Industrial PLC I/O Expansion Hub |
|---|---|
Use Scenario: Implementing address decoding, interrupt arbitration, and configuration space access for PCIe-to-PCI bridge cards. IC Role / Device Role / Timing Role: CPLD acts as static logic controller managing PCI command/address latching, DEVSEL# assertion, and parity generation with deterministic 66 ns tPD. Use Value: JTAG reprogrammability allows late-stage protocol tweaks without PCB respin; 5V-tolerant I/Os interface directly with legacy PCI slots. | Use Scenario: Aggregating and conditioning discrete 24V DC sensor/actuator signals into a synchronized parallel bus for microcontroller polling. IC Role / Device Role / Timing Role: Performs level translation, debouncing, and state-based signal conditioning using buried macrocells as input registers and I/O macrocells as drivers. Use Value: Bus-hold prevents floating inputs during sensor disconnect; programmable slew rate reduces conducted noise on long industrial cables. |
| Legacy Bus Bridge (ISA/LPC to SPI) | Automotive Body Control Module Glue Logic |
Use Scenario: Translating ISA timing and signaling to modern SPI-based peripheral controllers in embedded test equipment. IC Role / Device Role / Timing Role: Implements cycle-stealing DMA handshaking, wait-state insertion, and address decode with four independent clock domains. Use Value: Four dedicated clocks enable simultaneous ISA bus timing, SPI master clock, and internal state-machine clocks - no external clock dividers needed. | Use Scenario: Managing door lock actuation sequencing, mirror position latching, and window up/down safety logic in 12V automotive ECUs. IC Role / Device Role / Timing Role: CPLD executes fail-safe combinational and registered logic with asynchronous reset, using PTCLK for emergency stop triggers. Use Value: Asynchronous set/reset product terms ensure immediate response to crash or power-fail events - independent of main clock domain. |
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 |
|---|---|---|---|
| AMD XC95512-10PQ208C | 5V-only supply; 208-pin PQFP; 10 ns tPD; no 5V-tolerant I/Os on 3.3V rails | Requires level shifters for mixed-voltage systems; lacks bus-hold and programmable slew | Prefer when legacy 5V-only designs dominate and JTAG reprogramming is secondary |
| Lattice ispMACH 4A512V-10T176 | 3.3V supply; 176-pin TQFP; 10 ns tPD; IEEE 1532 ISP but no PCI compliance documentation | Smaller I/O count (133); no published PCI electrical validation; different PIM routing model | Prefer when board space is constrained and PCI compliance is not required |

FAQ
Is CY37512VP256-66BGC compatible with 5V I/O buses?
Yes. All I/O pins are 5V-tolerant regardless of VCCO setting. When VCCO = 3.3V, outputs meet 3.3V JEDEC CMOS levels while safely accepting 5V inputs - eliminating external level shifters in mixed-voltage PCI or ISA interfaces.
Does this device require external configuration memory?
No. CY37512VP256-66BGC is non-volatile and retains its configuration without external memory. Configuration is stored in on-chip EEPROM and loaded automatically at power-up; JTAG reprogramming writes directly to internal flash.
Can I migrate a design from CY37256V to CY37512VP256-66BGC without PCB changes?
Yes. Both devices share identical 256-pin FBGA (BGC) package and pinout. The additional macrocells and I/Os in CY37512V are enabled via unused pins in the CY37256V footprint - allowing seamless hardware scalability without layout revision.
What development tools support this device?
Cypress Warp v6.0+ and third-party tools including Mentor Graphics Precision RTL, Synopsys Synplify Pro, and Xilinx ISE (via CPLD plugin) fully support CY37512VP256-66BGC synthesis, place-and-route, and JTAG programming - with timing models validated to the 66 ns spec.
