Infineon Technologies CY62136EV30LL-45BVXIT

Overview

CY62136EV30LL-45BVXIT from Infineon Technologies (formerly Cypress) is a 2-Mbit (128K × 16) CMOS static RAM with 45 ns access time, 2.2–3.6 V supply range, and ultra-low standby current (1 µA typical). It operates in industrial temperature range (–40 °C to +85 °C) and is packaged in a Pb-free 48-ball VFBGA. It serves as main data buffer in portable embedded systems requiring fast, low-power volatile memory.

For engineers reviewing the CY62136EV30LL-45BVXIT datasheet, CY62136EV30LL-45BVXIT pinout, CY62136EV30LL-45BVXIT application, or CY62136EV30LL-45BVXIT equivalent, key selection criteria include guaranteed 45 ns read/write timing at 3.6 V, byte-level write enable (BHE/ BLE), automatic CE power-down mode, and VFBGA package compatibility with high-density PCB layouts.

Technical Context

The device implements a fully static 128K × 16-bit RAM array with independent byte-wide write control via BHE and BLE inputs, enabling partial-word writes without external logic. Its CMOS architecture supports true dual-cycle operation: read cycles require CE and OE LOW with WE HIGH, while write cycles require CE and WE LOW with appropriate byte enables.

It features two distinct low-power states: ISB1/ISB2 standby modes activate when CE is HIGH and all control inputs are held at valid CMOS levels, reducing ICC to ≤7 µA; data retention remains functional down to VCC = 1.0 V with ICCDR ≤3 µA. Address and I/O pins enter high-impedance state during deselection, output disable, or write operations.

FAQ

What is the minimum VCC required to retain data in CY62136EV30LL-45BVXIT?

Data retention is guaranteed down to VCC = 1.0 V, with ICCDR ≤3 µA under those conditions. The device enters data retention mode automatically when CE is HIGH and VCC drops below operating range, preserving stored content without external intervention or clocking.

Can CY62136EV30LL-45BVXIT be used with a 2.5 V-only system?

Yes - its specified VCC range is 2.2 V to 3.6 V, fully covering 2.5 V nominal rails. All AC and DC parameters, including 45 ns access time and 1 µA standby current, are validated across this range, with no derating required at 2.5 V.

How does byte enable (BHE/ BLE) affect power consumption during partial writes?

Asserting only BHE or BLE reduces active current by ~30% compared to full 16-bit writes, as only half the internal sense amplifier and data driver circuitry is activated. This directly lowers dynamic power in applications performing frequent 8-bit updates like protocol stack buffers.

Is the 48-ball VFBGA package lead-free and RoHS-compliant?

Yes - the CY62136EV30LL-45BVXIT is manufactured in a Pb-free, RoHS-compliant 48-ball VFBGA package with matte tin finish on solder balls, meeting JEDEC J-STD-020D moisture sensitivity level 3 (MSL3) requirements.
