Product details
Overview
CY37512VP256-83BGC from Cypress Semiconductor is a 3.3V In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in the Ultra37000 family, featuring 512 macrocells, 264 I/O pins, and a 15 ns maximum propagation delay (tPD). It supports JTAG-based reconfiguration without pinout or timing changes, includes programmable bus-hold on all I/Os, and operates with 3.3V VCC and 5V-tolerant I/Os - used in PCI-compliant interface logic, FPGA configuration glue, and legacy bus bridging.
For engineers reviewing the CY37512VP256-83BGC datasheet, CY37512VP256-83BGC pinout, CY37512VP256-83BGC application, or CY37512VP256-83BGC equivalent, key selection criteria include its 512-macrocell density, 15 ns speed bin (83 MHz fMAX), 3.3V core supply with 5V-tolerant I/Os, JTAG ISR capability, and support for product-term clocking and flexible logic block-level clock polarity control.
Technical Context
The CY37512VP256-83BGC implements a modular architecture with multiple logic blocks interconnected via a fully global Programmable Interconnect Matrix (PIM), where all inputs-including I/O feedbacks and dedicated pins-pass through the PIM with fixed, route-independent timing. Each logic block contains a 72×87 product term array, intelligent allocator supporting 0–16 product terms per macrocell, and four synchronous clocks plus one asynchronous product-term clock (PTCLK).
It features 16 macrocells per logic block (mix of I/O and buried), programmable slew rate per output, configurable bus-hold on all I/Os, and dual-mode logic blocks (high-speed or low-power). The device uses dedicated input/clock pins with polarity-controlled clock paths and supports combinatorial, registered, double-registered, or latched input configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 512 macrocells across multiple logic blocks - enables large-scale combinational and sequential logic implementation without external glue logic. |
| Maximum Propagation Delay (tPD) | 15 ns - guarantees deterministic timing for critical path logic at up to 83 MHz system clock frequency. |
| I/O Pins | 264 user-programmable I/Os - supports wide parallel bus interfaces including PCI Local Bus and memory-mapped peripherals. |
| Supply Voltage | 3.3V VCC with 5V-tolerant I/Os - allows direct interfacing to both 3.3V and 5V systems without level shifters. |
| Programmable Features | JTAG-based In-System Reprogrammability (ISR™), bus-hold on all I/Os, slew-rate control, and logic-block-level power mode selection - reduces board complexity and supports field updates. |
| Logic Block Clocking | Four global synchronous clocks (CLK0–CLK3) + one asynchronous product-term clock (PTCLK), each with programmable polarity - enables mixed-edge-triggered and asynchronous control schemes. |
Pinout & Package
This device is packaged in a 256-pin Fine-Pitch Ball Grid Array (FBGA) with 1.0 mm pitch, RoHS-compliant and lead-free. Pin assignments follow Cypress' consistent Ultra37000 family pinout scheme across densities and voltage grades.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TCK, TMS, TDI, TDO | JTAG boundary scan and ISR programming interface | Enables in-circuit reprogramming and IEEE 1149.1-compliant test access without requiring device removal. |
| VCC, VCCO, GND | Power and ground distribution | VCC = 3.3V core supply; VCCO = I/O supply (3.3V only for this 3.3V variant); separate VCCO pins allow mixed-voltage I/O banks in compatible devices. |
| CLK0–CLK3 | Dedicated synchronous clock inputs | Four globally distributed clocks with per-block polarity control - supports multi-clock domain designs and phase-aligned register transfers. |
| IO[0]–IO[263] | Configurable bidirectional I/O terminals | All support programmable bus-hold, slew rate, pull-up/down disable, and input register/latch modes - eliminates need for external termination in bus-hold applications. |
| PTCLK | Asynchronous product-term clock input | Allows dynamic clock enable/disable based on internal logic conditions - enables event-driven state machine transitions independent of global clocks. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | JTAG-based reconfiguration preserves pinout and timing across design iterations - accelerates prototyping and enables field firmware updates without hardware change. |
| Intelligent Product Term Allocator | Assigns 0–16 product terms per macrocell and enables sharing/steering across local macrocell groups - maximizes logic utilization without performance penalty. |
| Flexible Clock Architecture | Four synchronous clocks + one asynchronous product-term clock, each with polarity control - supports mixed-edge flip-flops and asynchronous event capture within same logic block. |
| Programmable Bus-Hold | Active weak latch on every I/O pin - maintains last valid logic state during high-Z periods, eliminating external pull-ups and reducing noise in shared-bus environments. |
| PCI-Compliant Electrical Interface | Meets PCI Local Bus Specification electrical and timing requirements - certified for use as bridge logic, address decoder, or bus controller in PCI add-in cards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based interface and glue logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMD XC95512-10PQ208C | 5V-only operation, 10 ns tPD, 208-pin PQFP package, no bus-hold, no 5V-tolerant I/Os | Limited to 5V-only systems; lacks JTAG ISR and programmable I/O features - requires external pull-ups and level shifters for mixed-voltage designs | Select when legacy 5V infrastructure dominates and JTAG reprogrammability is not required. |
| Lattice ispMACH 4A512V-10T176I | 3.3V core, 10 ns tPD, 176-pin TQFP, supports IEEE 1532 programming but no bus-hold or PCI compliance certification | Smaller I/O count (133 pins), no dedicated PCI timing validation - suitable for general-purpose logic but not certified for PCI slot deployment | Choose for cost-sensitive, space-constrained designs where PCI compliance and 264 I/Os are unnecessary. |

FAQ
Is CY37512VP256-83BGC compatible with 5V logic levels?
Yes - all I/O pins are 5V-tolerant when VCCO = 3.3V, meaning they accept 5V input signals without damage and meet 3.3V JEDEC CMOS output levels. However, the core VCC must remain at 3.3V; this is not a 5V-core device like the CY37512-83BGC variant.
Does this device require external configuration memory?
No - CY37512VP256-83BGC contains on-chip nonvolatile configuration memory and boots autonomously. It does not rely on external PROM or flash; configuration is stored internally and loaded at power-up without host intervention.
Can the JTAG interface be used for both programming and boundary-scan testing?
Yes - the device implements full IEEE 1149.1 boundary-scan architecture alongside ISR functionality. TCK, TMS, TDI, and TDO pins support both in-system programming and structural test, enabling production test and debug without additional hardware.
What is the maximum operating temperature range for this FBGA package?
The CY37512VP256-83BGC in the 256-pin FBGA (BGC suffix) is rated for commercial temperature range (0°C to +70°C). Industrial-grade variants (e.g., with 'I' suffix) are not available for this specific speed bin and package combination.
