Infineon Technologies CY37192P160-83AXI

Overview

CY37192P160-83AXI from Cypress Semiconductor is a 192-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, operating at 5V with 83 ns maximum propagation delay (tPD), 154 MHz maximum frequency (fMAX), and 120 user I/O pins in a 160-lead TQFP package. It implements logic blocks interconnected via a Programmable Interconnect Matrix (PIM), supports JTAG-based reconfiguration without pinout or timing changes, and targets high-reliability board-level logic replacement and glue logic consolidation in industrial control systems.

For engineers reviewing the CY37192P160-83AXI datasheet, CY37192P160-83AXI pinout, CY37192P160-83AXI application, or CY37192P160-83AXI equivalent, key selection criteria include macrocell count, I/O count, tPD/fMAX speed bin, VCC/VCCO voltage configuration, bus-hold enablement, and JTAG boundary-scan compliance for in-system programming and test.

Technical Context

The CY37192P160-83AXI integrates six logic blocks, each with a 72×87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells-supporting combinatorial, registered, latched, or T-flip-flop configurations. All macrocells access four global synchronous clocks (CLK0–CLK3) and one asynchronous product term clock (PTCLK), with programmable polarity per clock.

Its Programmable Interconnect Matrix (PIM) delivers 36 dedicated inputs per logic block (plus complements), eliminates fanout/expander delays, and embeds worst-case PIM routing delay into published tPD specifications-ensuring route-independent timing across all designs. Dedicated input pins include four clock-capable inputs and one general-purpose input, all configurable as combinatorial, registered, double-registered, or latched.

FAQ

Is CY37192P160-83AXI compatible with 3.3V I/O standards?

Yes. The device operates from a 5V VCC supply but supports 3.3V I/O levels when VCCO pins are connected to 3.3V. Its outputs meet JEDEC 3.3V CMOS specifications and are 5V-tolerant, enabling safe interfacing with both 3.3V and 5V subsystems without level shifters.

Does CY37192P160-83AXI require external programming hardware?

No. It features a fully compliant IEEE 1149.1 JTAG interface (TCK, TMS, TDI, TDO) that supports in-system reprogramming and boundary-scan testing using standard JTAG adapters-no dedicated programming socket or UV eraser is needed.

What is the purpose of the PTCLK pin?

PTCLK is an asynchronous product term clock input that allows logic updates triggered by internal combinational conditions rather than system clocks. It enables event-driven behavior such as glitch-free reset assertion, interrupt acknowledgment, or dynamic mode switching without relying on external clock sources.

Can unused I/O pins be left unconnected?

Yes. All I/O pins support programmable bus-hold, which maintains their last driven state when tri-stated. This eliminates the need for external pull-up/down resistors and allows safe floating of unused pins-particularly beneficial during prototyping and board reuse.
