Infineon Technologies CY37064P100-200AXC

Overview

CY37064P100-200AXC from Cypress Semiconductor is a 64-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, operating at 5V with 100-pin TQFP package and 200 MHz maximum frequency (f_MAX). It features four synchronous clocks, programmable bus-hold on all I/Os, and JTAG-compliant ISR for field reconfiguration without pinout or timing changes - used in PCI-compliant interface logic, glue logic replacement, and system boot configuration.

For engineers reviewing the CY37064P100-200AXC datasheet, CY37064P100-200AXC pinout, CY37064P100-200AXC application, or CY37064P100-200AXC equivalent, key selection criteria include macrocell count, I/O pin count (69 usable), t_PD = 6 ns, 5V/3.3V I/O tolerance, and JTAG-based in-system reprogrammability for rapid design iteration and production flexibility.

Technical Context

The CY37064P100-200AXC implements a modular architecture with two logic blocks, each containing a 72×87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells (mix of I/O and buried). Its Programmable Interconnect Matrix (PIM) delivers fixed, route-independent timing by routing all signals-including macrocell feedbacks and dedicated inputs-through a global matrix with worst-case delays embedded in published specs.

It supports flexible clocking via four global synchronous clocks (CLK0–CLK3) plus one asynchronous product term clock (PTCLK), all with programmable polarity; dedicated input pins include four clock-capable inputs and one general-purpose input; bus-hold and slew-rate control are per-I/O configurable to reduce noise and simplify board layout in mixed-voltage systems.

FAQ

What voltage levels does CY37064P100-200AXC support on its I/O pins?

CY37064P100-200AXC supports both 5V and 3.3V I/O signaling through separate V_CCO pins. When V_CCO is tied to 5V, outputs meet 5V TTL levels; when tied to 3.3V, outputs comply with 3.3V JEDEC CMOS standards and remain 5V-tolerant. Core logic operates at 5V V_CC.

Does CY37064P100-200AXC require external configuration memory?

No. CY37064P100-200AXC contains on-chip nonvolatile configuration memory and powers up fully operational without external PROM or flash. Configuration is retained after power cycling, and reprogramming occurs in-system via JTAG without disrupting system operation.

Can CY37064P100-200AXC replace older 22V10 PAL devices in existing designs?

Yes - its architecture extends the 22V10 paradigm with higher density and ISR capability. Pin-compatible migration is feasible for many 22V10-based designs using the same 100-pin TQFP footprint, though logic equations must be recompiled using Warp or third-party tools to leverage macrocell and PIM resources.

Is boundary scan testing supported on CY37064P100-200AXC?

Yes. CY37064P100-200AXC implements full IEEE 1149.1 boundary scan functionality via its TCK/TMS/TDI/TDO pins. This enables automated PCB test, interconnect verification, and in-circuit debugging without requiring additional test fixtures or probe points.
