Product details

Overview

CY37128VP160-83AXI from Cypress Semiconductor is a 128-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, operating at 3.3V with 160-pin TQFP packaging. It delivers 125 MHz maximum frequency (f_MAX), 10 ns propagation delay (t_PD), and supports 128 I/O pins with programmable bus-hold, slew-rate control, and four synchronous clocks per logic block. It is used in PCI-compliant interface glue logic, FPGA configuration management, and legacy bus bridging.

For engineers reviewing the CY37128VP160-83AXI datasheet, CY37128VP160-83AXI pinout, CY37128VP160-83AXI application, or CY37128VP160-83AXI equivalent, key selection criteria include its 3.3V operation with 5V-tolerant I/Os, JTAG-based ISR capability, fixed-pinout migration path across densities, and support for product-term steering and sharing without timing penalty.

Technical Context

The CY37128VP160-83AXI implements a multi-block architecture with two logic blocks, each containing a 72×87 product term array, intelligent product term allocator, and 16 macrocells (mix of I/O and buried). Its Programmable Interconnect Matrix (PIM) provides 36 global inputs per logic block and eliminates route-dependent delays by incorporating worst-case PIM propagation into all timing specs.

Each macrocell supports 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 programmable polarity product-term clock (PTCLK). All I/Os feature configurable slew rate (fast/slow) and bus-hold latching to maintain last state during high-Z conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Macrocell Count	128 total macrocells distributed across two logic blocks - defines maximum combinational/registered logic capacity.
Maximum Frequency (f_MAX)	125 MHz - sets upper limit for synchronous logic operation under worst-case timing conditions.
Propagation Delay (t_PD)	10 ns - guaranteed max delay from input to registered output, independent of fanout or product-term usage.
I/O Pins	128 user-configurable I/Os - supports wide parallel interfaces such as PCI, ISA, or memory-mapped peripherals.
Supply Voltage	3.3V V_CC, 3.3V V_CCO - enables direct interfacing with 3.3V JEDEC CMOS buses while maintaining 5V tolerance on all I/Os.
ISR Programming Voltage	3.3V - allows in-system reconfiguration without external 5V programming supply.
Package	160-pin TQFP (24×24 mm, 0.5 mm pitch) - surface-mount package compatible with standard reflow processes and automated assembly.

Pinout & Package

Package: 160-pin Thin Quad Flat Package (TQFP), 24 mm × 24 mm body, 0.5 mm lead pitch, RoHS-compliant and lead-free option available.

Pin/Terminal	Circuit Role	Design Meaning
TCK, TMS, TDI, TDO	JTAG boundary-scan and ISR interface	Enable IEEE 1149.1-compliant programming, debugging, and in-system reconfiguration without disrupting system operation.
CLK0–CLK3	Dedicated synchronous clock inputs	Four globally distributed clocks per logic block; each supports programmable polarity for rising/falling-edge triggering.
IO[0]–IO[127]	Configurable bidirectional I/O	Supports input, output, or bidirectional modes; each includes bus-hold latch and fast/slow slew-rate control.
V_CC, V_CCO, GND	Power and ground terminals	V_CC = 3.3V core supply; V_CCO = 3.3V I/O supply enabling 5V-tolerant operation; multiple GND pins reduce switching noise.

Key Features

Feature	Design Value
In-System Reprogrammability (ISR™)	JTAG-based field updates without board removal - preserves pinout and timing across design iterations.
Intelligent Product Term Allocator	Assigns 0–16 product terms per macrocell and enables sharing across groups of four macrocells - maximizes logic utilization without speed penalty.
Programmable Slew Rate	Per-pin fast/slow edge control - reduces EMI in noise-sensitive environments or boosts timing margin in high-speed paths.
Bus-Hold on All I/Os	Internal weak latch maintains last logic state during high-Z - eliminates need for external pull-ups and simplifies prototyping.
PCI Compliance	Meets electrical and timing requirements of PCI Local Bus Specification Rev. 2.2 - enables direct integration into PCI add-in cards and host bridges.

Applications

PCI Interface Glue Logic

FPGA Configuration Manager

Use Scenario: Implementing address decoding, bus arbitration, and protocol translation between a PCI host controller and legacy peripherals.

IC Role / Device Role / Timing Role: CPLD acts as synchronous bridge logic with deterministic 10 ns t_PD, handling setup/hold timing for PCI 33 MHz transfers.

Use Value: Fixed pinout allows hardware reuse across firmware revisions; ISR enables late-stage protocol tweaks without PCB respin.

Use Scenario: Storing and loading configuration bitstreams into Xilinx or Altera FPGAs during power-up or dynamic reconfiguration.

IC Role / Device Role / Timing Role: Nonvolatile CPLD serves as serial PROM replacement with parallel access and JTAG update capability.

Use Value: 128 macrocells support multi-FPGA sequencing logic; 3.3V/5V-tolerant I/Os interface directly with diverse FPGA configuration pins.

Legacy Bus Bridging

Industrial Control Sequencer

Use Scenario: Translating between ISA, LPC, or parallel port signals and modern microcontroller buses in industrial instrumentation.

IC Role / Device Role / Timing Role: Combinatorial and registered logic handles handshaking, strobe generation, and data alignment across asynchronous domains.

Use Value: Four dedicated clocks and product-term clocking enable precise timing control for mixed-speed peripherals.

Use Scenario: Replacing discrete 74-series logic and PALs in PLC I/O modules for sensor conditioning and actuator timing.

IC Role / Device Role / Timing Role: State-machine-based sequencer managing relay drive timing, watchdog resets, and fault detection with asynchronous set/reset.

Use Value: Buried macrocells provide internal registers for state storage; bus-hold prevents floating inputs in noisy factory environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar CPLD-based interface logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LC4128V-75TN100C (Lattice)	128 macrocells, 75-pin TQFP, 3.3V, 125 MHz f_MAX; uses ISP via JTAG but lacks dedicated product-term clock and bus-hold.	Requires external pull-ups for unused I/Os; no built-in PCI compliance testing documentation.	Preferred when lower cost and smaller footprint are prioritized over bus-hold and PCI-certified timing margins.
ATF1504AS-10QU100 (Microchip)	128 macrocells, 100-pin TQFP, 3.3V, 100 MHz f_MAX; supports JTAG ISP but has fixed 8-product-term limit per macrocell and no slew-rate control.	Limited routing flexibility due to fixed product-term allocation; slower max frequency restricts use in 33 MHz PCI timing-critical paths.	Selected for cost-sensitive, non-PCI applications where 100 MHz timing suffices and external slew filtering is acceptable.

Compared with LC4128V-75TN100C and ATF1504AS-10QU100, the CY37128VP160-83AXI offers superior timing predictability (no fanout/expander delays), integrated bus-hold eliminating BOM components, and verified PCI electrical compliance - making it optimal for industrial and embedded systems requiring field-upgradable, noise-resilient glue logic.

FAQ

What voltage levels does CY37128VP160-83AXI support on its I/O pins?

The device operates from a 3.3V V_CC supply and requires 3.3V on all V_CCO pins. Its I/Os are fully 5V-tolerant regardless of V_CCO level, meeting 3.3V JEDEC CMOS output standards while safely interfacing with 5V signaling systems without level shifters.

Can CY37128VP160-83AXI be reprogrammed while installed on a live circuit board?

Yes - it supports full In-System Reprogrammability (ISR™) via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO). Reprogramming occurs at 3.3V and preserves existing pin assignments and timing behavior, enabling firmware updates and logic fixes without board removal or power cycling.

How many logic blocks and macrocells are implemented in this specific device?

CY37128VP160-83AXI contains two logic blocks, each with 64 macrocells (128 total). Each logic block includes a 72×87 product term array, intelligent allocator, and dedicated resources including four synchronous clocks, asynchronous set/reset, and product-term clocking capability.

Does this CPLD require external pull-up or pull-down resistors on unused I/O pins?

No - all I/O pins feature programmable bus-hold circuitry, which acts as an internal weak latch to retain the last driven logic state during high-impedance conditions. This eliminates the need for external resistors, reduces BOM count, and improves noise immunity in unconnected or floating-pin scenarios.
