Infineon Technologies CY62126EV30LL-55BVXET

Overview

CY62126EV30LL-55BVXET from Cypress Semiconductor is a 1-Mbit (64K × 16) CMOS static RAM with 55 ns access time, 2.2–3.6 V supply range, and industrial temperature rating (–40 °C to +85 °C). It features ultra-low standby current (1 µA typical), automatic CE-controlled power-down, and byte-wide I/O (I/O0–I/O7 and I/O8–I/O15) for selective data access in portable memory subsystems.

For engineers reviewing the CY62126EV30LL-55BVXET datasheet, CY62126EV30LL-55BVXET pinout, CY62126EV30LL-55BVXET application, or CY62126EV30LL-55BVXET equivalent, key selection criteria include its VFBGA-48 package compatibility, 16-bit data bus width, low-voltage operation down to 2.2 V, and guaranteed 55 ns timing under industrial conditions.

Technical Context

The CY62126EV30LL-55BVXET implements a full CMOS SRAM array with independent byte enable (BHE/ BLE) control, enabling partial-word writes without disturbing adjacent bytes. Its automatic power-down logic activates when CE is HIGH and address lines are stable, reducing ICC to ≤4 µA.

It supports asynchronous read/write operations with separate OE, WE, CE, and byte-enable timing paths. All switching parameters-including tACE (55 ns), tDOE (25 ns), and tHZOE (20 ns)-are specified over the full industrial voltage (2.2–3.6 V) and temperature (–40 °C to +85 °C) range.

FAQ

What is the minimum VCC required to retain data in CY62126EV30LL-55BVXET?

The device guarantees data retention down to 1.5 V (VDR), as specified in the Data Retention Characteristics table. At this voltage, ICCDR remains ≤3 µA under industrial conditions. This enables operation from backup batteries or supercapacitors during main power loss, provided CE is held HIGH and inputs are within valid logic thresholds.

Can CY62126EV30LL-55BVXET operate reliably at 2.2 V across the full industrial temperature range?

Yes. The datasheet specifies all AC and DC parameters-including 55 ns access time, 1.3 mA active current, and 4 µA max standby current-at VCC = 2.2 V and TA = –40 °C to +85 °C. No derating or external compensation is required for full functionality at minimum supply voltage.

How does automatic power-down activate, and what signals must be controlled?

Automatic power-down engages when CE is HIGH and all address inputs (A0–A15) are stable (no toggling). Input levels on OE, WE, BHE, and BLE do not affect entry-only CE and address stability matter. Outputs enter high-Z immediately, and ICC drops to ≤4 µA without requiring external sequencing logic.

Is the VFBGA-48 package of CY62126EV30LL-55BVXET compatible with standard reflow profiles?

Yes. The device is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles with peak temperatures up to 260 °C. Thermal resistance values (θJA = 58.85 °C/W, θJC = 17.01 °C/W) are measured on a 2-layer PCB per JEDEC standards, confirming manufacturability in high-volume SMT lines.
