Product details
Overview
CY37256VP160-100AXI from Cypress Semiconductor is a 256-macrocell, In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in a 160-pin TQFP package, operating at 5V with 100 MHz maximum frequency (fMAX) and 7.5 ns propagation delay (tPD). It features four synchronous clocks, programmable bus-hold on all I/Os, and supports PCI Local Bus electrical compliance. Used for glue logic replacement and control plane implementation in industrial control backplanes.
For engineers reviewing the CY37256VP160-100AXI datasheet, CY37256VP160-100AXI pinout, CY37256VP160-100AXI application, or CY37256VP160-100AXI equivalent, key selection criteria include macrocell count, I/O pin count (160), JTAG-based ISR capability, 5V supply operation, and PCI-compatible timing margins.
Technical Context
The CY37256VP160-100AXI implements the Ultra37000 architecture with a Programmable Interconnect Matrix (PIM) distributing up to 36 signals per logic block and supporting full macrocell feedback routing. Its logic blocks each contain a 72 × 87 product term array, intelligent allocator assigning 0–16 product terms per macrocell, and dedicated asynchronous set/reset product terms.
It supports flexible clocking via four global synchronous clocks (CLK0–CLK3) plus one product-term clock (PTCLK), all with programmable polarity. All 160 I/O pins feature user-configurable bus-hold and slew-rate control (fast/slow), and the device uses JTAG-compliant boundary scan for both programming and test.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 256 - Provides combinational and registered logic capacity for medium-complexity state machines and protocol translators. |
| I/O Pins | 160 - Enables high-pin-count interface bridging between processors, memory, and peripherals without external logic. |

| OE[0:3] | Output Enable Controls | Four product-term-driven OE signals, each controlling up to eight macrocells-enables dynamic I/O direction control. |
| VCC, GND | Power & Ground | Multiple distributed VCC/GND pairs minimize switching noise and ensure stable CPLD core operation. |
| VCCO[0:3] | I/O Power Supply | Four separate VCCO banks allow mixed-voltage I/O (3.3V/5V) on same device for heterogeneous bus interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammable (ISR™) | JTAG-based field updates preserve pinout and timing-eliminates PCB respins during firmware logic iteration. |
| Intelligent Product Term Allocator | Dynamically assigns 0–16 product terms per macrocell and enables sharing across groups of four macrocells-maximizes logic utilization without speed penalty. |
| Programmable Slew Rate | Fast/slow edge selection per output-reduces EMI in noise-sensitive environments while maintaining performance where needed. |
| Bus-Hold on All I/Os | Weak latch maintains last valid logic state on floating inputs-prevents undefined states in unconnected or tri-stated bus lines. |
| Consistent Pinout Across Densities | Same 160-pin TQFP footprint used for CY37128, CY37192, and CY37256 devices-enables hardware scalability without layout change. |

FAQ
What voltage levels does CY37256VP160-100AXI support on its I/O pins?
CY37256VP160-100AXI operates from a 5V VCC supply and supports both 5V TTL and 3.3V CMOS I/O levels. Its four VCCO pins can be independently tied to either 5V or 3.3V to configure corresponding I/O banks-enabling mixed-voltage interfacing without external level shifters.
Does CY37256VP160-100AXI require external configuration memory?
No. CY37256VP160-100AXI contains on-chip nonvolatile EEPROM for configuration storage. It powers up fully operational without external PROM or flash memory, and retains logic configuration indefinitely after power removal.
Can CY37256VP160-100AXI replace older CY37128 or CY37192 devices on the same PCB?
Yes. The Ultra37000 family maintains identical pinouts across densities in the same package. A 160-pin TQFP CY37128 or CY37192 can be upgraded to CY37256VP160-100AXI without PCB modification-only the JEDEC file and programming tool settings require update.
Is JTAG programming supported for both configuration and boundary-scan testing?
Yes. CY37256VP160-100AXI implements full IEEE 1149.1 JTAG functionality: TAP controller supports INTEST, EXTEST, SAMPLE/PRELOAD, and BYPASS instructions, enabling both in-system reconfiguration and structural board-level test without additional test fixtures.
