Infineon Technologies CY37192VP160-66AXC

Overview

CY37192VP160-66AXC from Cypress Semiconductor is a 3.3V In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, featuring 192 macrocells, 120 user I/O pins, and a 160-lead TQFP package. It supports 3.3V JEDEC CMOS output levels with 5V-tolerant I/Os, programmable bus-hold on all I/Os, and four synchronous clocks per logic block. It is used in PCI-compliant interface logic, legacy bus bridging, and FPGA configuration management.

For engineers reviewing the CY37192VP160-66AXC datasheet, CY37192VP160-66AXC pinout, CY37192VP160-66AXC application, or CY37192VP160-66AXC equivalent, key selection criteria include tPD = 12 ns, fMAX = 100 MHz, 3.3V supply operation with 5V-tolerant I/Os, JTAG-based ISR capability, and programmable slew rate control per output.

Technical Context

The CY37192VP160-66AXC implements a modular architecture with multiple logic blocks interconnected via a fully global Programmable Interconnect Matrix (PIM), eliminating route-dependent timing variations. 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 features five dedicated input pins-including four clock-capable inputs-with configurable polarity and double-register support. Clocking includes four global synchronous clocks (CLK0–CLK3), one asynchronous product term clock (PTCLK), and per-block clock polarity control. All I/Os support programmable bus-hold and slew rate (fast/slow).

FAQ

Is CY37192VP160-66AXC compatible with 5V I/O buses?

Yes. The device has 5V-tolerant I/Os when VCCO is set to 3.3V, allowing direct connection to 5V signaling environments without external level shifters. This tolerance is specified per JEDEC Std 8-10A and verified across commercial temperature range (0°C to 70°C). Input thresholds meet PCI VIH ≥ 2.0V and VIL ≤ 0.8V under 3.3V VCCO conditions.

What programming tools support CY37192VP160-66AXC ISR functionality?

Cypress Warp v7.0+ and third-party tools including Lattice ispLEVER Classic and Mentor Graphics Precision RTL support JTAG-based programming and debugging. The device implements IEEE 1149.1 boundary scan and requires a standard JTAG cable (e.g., ByteBlaster MV or USB-Blaster) with SVF or STAPL file format compatibility.

Does CY37192VP160-66AXC support hot-swap I/O behavior?

Yes. All I/Os feature programmable bus-hold, which maintains the last driven logic state during high-impedance transitions-critical for hot-plug scenarios. Bus-hold current is ±100 µA typical, and activation is controlled per-pin via configuration bit. No external pull resistors are needed, reducing BOM count and PCB area.

How does the PIM architecture affect timing predictability?

The Programmable Interconnect Matrix (PIM) eliminates route-dependent delays by providing fixed, worst-case propagation delay values incorporated into all published timing specs (e.g., tPD = 12 ns). All signals-including feedback paths and dedicated inputs-pass through the PIM, so timing is invariant regardless of logic placement or routing density, enabling deterministic static timing analysis.
