Product details
Overview
CY37128P100-125AXIT from Cypress Semiconductor is a 128-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, operating at 5V with 125 MHz maximum frequency (tPD = 12.5 ns), 100-pin TQFP package, and 133 I/O pins. It features four synchronous clocks per logic block, programmable bus-hold on all I/Os, and JTAG-compliant ISR for field reconfiguration without pinout or timing changes - used in PCI-compliant interface glue logic and legacy system upgrades.
For engineers reviewing the CY37128P100-125AXIT datasheet, CY37128P100-125AXIT pinout, CY37128P100-125AXIT application, or CY37128P100-125AXIT equivalent, key selection criteria include macrocell count, I/O count, tPD/fMAX speed bin, VCCO voltage flexibility (5V/3.3V I/O support), and JTAG-based in-system reprogrammability for hardware iteration.
Technical Context
The CY37128P100-125AXIT implements a multi-block architecture with two logic blocks, each containing 16 macrocells and a 72×87 product term array. Its Programmable Interconnect Matrix (PIM) delivers fixed, route-independent timing by distributing 36 global inputs (plus complements) to each logic block with no fanout, expander, or PIM-path delay penalties.
Each macrocell supports combinatorial, D/T/latch register modes with asynchronous set/reset controlled by dedicated product terms, and clocking via four global synchronous clocks (CLK0–CLK3) or a product-term clock (PTCLK), all with programmable polarity. All I/Os feature configurable slew rate and bus-hold capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 128 total, distributed across two logic blocks - enables medium-complexity glue logic and state-machine implementation |
| Maximum Frequency (fMAX) | 125 MHz - supports synchronous operation up to 8 ns clock period in critical paths |
| Propagation Delay (tPD) | 12.5 ns - guaranteed worst-case path delay from input to registered output |
| I/O Pins | 133 - provides high pin density for bus interfacing and multi-peripheral control |
| Supply Voltage (VCC) | 5.0 V ± 10% - powers core logic; VCCO pins configurable for 5V or 3.3V I/O levels |
| Dedicated Inputs | 5 - includes four clock-capable pins and one general-purpose input, enabling flexible timing architecture |

CY37128P100-125AXIT contains two logic blocks, each with 64 macrocells, totaling 128 macrocells. Each logic block includes a 72×87 product term array, intelligent product term allocator, and dedicated clock and OE resources - confirmed in Cypress document #38-03007 Rev. *E.
Is CY37128P100-125AXIT compatible with PCI Local Bus Specification?
Yes. CY37128P100-125AXIT meets the electrical and timing requirements of the PCI Local Bus Specification, including VIH/VIL thresholds, drive strength, and setup/hold timing - explicitly stated in the "General Description" and "Features" sections of its official datasheet.
