Infineon Technologies CY7C1370KV25-200AXC

Overview

CY7C1370KV25 from Cypress Semiconductor is a 18-Mbit (512K × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory buffering in network packet processors and telecom line cards. It operates at 200 MHz with zero wait states, features 2.5 V core (VDD) and I/O (VDDQ) supplies, and delivers 3.2 ns clock-to-output delay. Its byte-write capability, JTAG boundary scan, and interleaved/linear burst modes support deterministic latency in back-to-back read/write transitions.

For engineers reviewing the CY7C1370KV25 datasheet, CY7C1370KV25 pinout, CY7C1370KV25 application, or CY7C1370KV25 equivalent, key selection criteria include its 512K × 36 organization, TQFP-100 or FBGA-165 packaging, synchronous self-timed write control, ZZ sleep mode, and compatibility with ZBT™-based system designs requiring sustained 200-MHz bus throughput.

Technical Context

The CY7C1370KV25 implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK, and all outputs pass through output registers synchronized to the same edge. Its NoBL™ logic eliminates bus latency by enabling true back-to-back read/write cycles without wait states.

It supports synchronous burst reads/writes (linear or interleaved), byte-selectable writes via four BWx signals controlling DQa–DQd and corresponding parity lines DQPa–DQPd, and low-power management via CEN-gated clocking and ZZ sleep mode. The device integrates IEEE 1149.1 JTAG boundary scan for production testability.

FAQ

What is the function of the MODE pin on CY7C1370KV25?

The MODE pin selects burst address order: tied HIGH for interleaved burst (e.g., cache line access), pulled LOW for linear burst (e.g., sequential DMA). It is a strap pin - must be stable during operation and defaults to HIGH if left floating. This configuration determines how ADV/LD increments the internal address counter during burst sequences.

How does the ZZ pin differ from CEN in power management?

CEN gates the clock synchronously to extend the previous cycle without changing device state, while ZZ asserts deep sleep mode asynchronously - disabling clocks, I/O drivers, and internal logic to minimize standby current. ZZ retains memory contents but requires reinitialization of timing upon wake-up; CEN preserves full pipeline state for immediate resumption.

Can CY7C1370KV25 operate with only VDD powered and VDDQ unpowered?

No. Both VDD (2.5 V core) and VDDQ (2.5 V I/O) must be powered within specification before applying CLK or any input signals. Operating with VDDQ unpowered violates absolute maximum ratings and risks latch-up or I/O damage, as DQ/DQP pins are not 5-V tolerant and require VDDQ for proper driver biasing.

Is the CY7C1370KV25 pin-compatible with ZBT™ SRAMs?

Yes - it is explicitly designed as pin-compatible and functionally equivalent to ZBT™ SRAMs (e.g., IDT72V2115 series). Identical pinout, timing behavior, and control protocol allow drop-in replacement in existing ZBT-based designs, provided VDD/VDDQ voltage compliance and layout parasitics meet 2.5 V requirements.
