Infineon Technologies CY37032P44-200AXC

Overview

CY37032P44-200AXC from Cypress Semiconductor is a 32-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in a 44-pin TQFP package, operating at 5V with 200 MHz maximum frequency and 6 ns propagation delay. It features four synchronous clocks, five dedicated inputs (including four clock pins), programmable bus-hold on all I/Os, and JTAG-compliant reconfiguration. It is used in PCI-compliant interface logic, legacy bus bridging, and system control state machines.

For engineers reviewing the CY37032P44-200AXC datasheet, CY37032P44-200AXC pinout, CY37032P44-200AXC application, or CY37032P44-200AXC equivalent, key selection criteria include its fixed-pinout migration path across Ultra37000 densities, zero-delay PIM routing, product-term steering (0–16 per macrocell), 5V/3.3V I/O tolerance via VCCO configuration, and JTAG-based ISR programming without timing or pinout impact.

Technical Context

The CY37032P44-200AXC implements a single logic block architecture with a 72 × 87 product term array feeding 16 macrocells, supported by a fully global Programmable Interconnect Matrix (PIM) that delivers 36 inputs per logic block and eliminates route-dependent timing variation. All signals-including I/O feedbacks and dedicated inputs-pass through the PIM, with worst-case delays embedded in published tPD and fMAX specs.

Each macrocell supports combinatorial, D/T/latch register modes with asynchronous set/reset controlled by dedicated product terms, and clock selection among four global synchronous clocks (CLK0–CLK3) or a product-term clock (PTCLK), all with programmable polarity. Bus-hold and slew-rate control are per-I/O configurable.

FAQ

Is CY37032P44-200AXC compatible with 3.3V I/O signaling?

Yes. The device uses VCCO pins to configure I/O voltage: connecting VCCO to 3.3V enables JEDEC-standard 3.3V CMOS outputs with 5V tolerance on all I/Os. Core logic remains 5V-powered, and ISR programming requires 5V on VCC. No level shifters are needed for mixed-voltage interfaces.

Does this device support boundary-scan testing?

Yes. CY37032P44-200AXC implements full IEEE 1149.1 boundary-scan functionality via its JTAG port (TCK, TMS, TDI, TDO). This enables board-level interconnect testing, in-system programming, and real-time I/O pin observation without additional test fixtures or probe access.

Can I migrate my design from CY37032P44-200AXC to a higher-density Ultra37000 device?

Yes. Cypress guarantees identical pinout across all 44-pin TQFP Ultra37000 devices (CY37032, CY37064, CY37128). Logic migration requires only recompilation-no PCB change, no timing revalidation, and no I/O remapping-due to the family's fixed-package scaling architecture.

What clock resources are available for internal logic?

The device provides four global synchronous clocks (CLK0–CLK3), each accessible to all macrocells with programmable polarity, plus one asynchronous product-term clock (PTCLK) derived from the local product term array. All clocks feed both I/O and buried macrocells, enabling mixed-edge and multi-domain synchronous design within a single logic block.
