Product details
Overview
CY37128VP100-83AXCT from Cypress Semiconductor is a 128-macrocell, 3.3V In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in a 100-pin TQFP package. It features four synchronous clocks, five dedicated inputs (including four clock pins), programmable bus-hold on all I/Os, and supports 128 I/O pins with 5V-tolerant CMOS outputs. It is designed for PCI-compliant digital control logic in embedded interface and glue-logic applications.
For engineers reviewing the CY37128VP100-83AXCT datasheet, CY37128VP100-83AXCT pinout, CY37128VP100-83AXCT application, or CY37128VP100-83AXCT equivalent, key selection criteria include tPD = 10 ns, fMAX = 125 MHz, 3.3V VCC operation with 5V-tolerant I/Os, JTAG-based ISR capability, and fixed-pinout migration across Ultra37000 densities.
Technical Context
The CY37128VP100-83AXCT implements a modular architecture with multiple logic blocks interconnected via a fully global Programmable Interconnect Matrix (PIM), eliminating route-dependent timing variation. Each logic block contains a 72 × 87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells-supporting combinatorial, registered, latched, or T/D-flip-flop configurations.
It supports flexible clocking: four global synchronous clocks (CLK0–CLK3) with programmable polarity, plus an asynchronous product-term clock (PTCLK). All I/Os feature user-programmable slew rate (fast/slow) and bus-hold, enabling robust signal integrity in shared-bus environments without external pull-ups.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based digital control logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LC4128V-75TN100C (Lattice) | 128 macrocells, 3.3V, 7.5 ns tPD, non-JTAG ISP (uses proprietary programming interface) | Lacks IEEE 1149.1 boundary scan; requires Lattice-specific tools and cables | Prefer when toolchain lock-in is acceptable and sub-7.5 ns timing is critical |
| XC95144XL-10TQ100I (Xilinx) | 144 macrocells, 3.3V, 10 ns tPD, JTAG ISP, but no bus-hold or programmable slew rate | Requires external pull-ups for floating I/Os; less EMI control flexibility | Prefer when higher macrocell count is needed and external components are acceptable |

FAQ
Is CY37128VP100-83AXCT compatible with 5V logic interfaces?
Yes. While operating from a 3.3V VCC supply, all I/O pins are 5V-tolerant and support 3.3V JEDEC CMOS output levels. When interfacing with 5V systems, no external level-shifting circuitry is required-provided VCCO is tied to 3.3V and input voltages remain within absolute maximum ratings (–0.5V to 5.5V).
Does this device support boundary-scan testing?
Yes. The CY37128VP100-83AXCT fully complies with IEEE 1149.1 (JTAG) standards. Its TCK, TMS, TDI, and TDO pins enable full boundary-scan testing, in-system programming, and device identification without requiring additional test fixtures or debug probes beyond standard JTAG hardware.
Can I migrate my design from CY37128-100AXC (5V version) to CY37128VP100-83AXCT?
Yes-pinout and logic functionality are identical between the 5V CY37128-100AXC and 3.3V CY37128VP100-83AXCT in the same 100-pin TQFP package. Migration requires only updating VCC from 5V to 3.3V and confirming that all connected peripherals accept 3.3V signaling levels or are 5V-tolerant.
What development tools support this CPLD?
Cypress Warp v6.0+ and third-party tools including Synplify Pro and Leonardo Spectrum support synthesis, fitting, and JTAG programming of the CY37128VP100-83AXCT. Device-specific libraries and timing models are included in the official Ultra37000 family support pack (Document #38-03007 Rev. *E).
