Infineon Technologies CY62126EV18LL-70BVXI

Overview

CY62126EV18LL-70BVXI from Cypress Semiconductor is a 1-Mbit (64 K × 16) low-voltage CMOS static RAM with 70 ns access time, 1.65–1.95 V supply range, and ultra-low standby current (max 4 µA). It features byte-wide control (BHE/ BLE), automatic power-down on deselect, and is optimized for battery-powered portable electronics requiring deterministic timing and minimal active/standby power.

For engineers reviewing the CY62126EV18LL-70BVXI datasheet, CY62126EV18LL-70BVXI pinout, CY62126EV18LL-70BVXI application, or CY62126EV18LL-70BVXI equivalent, key selection criteria include industrial temperature support (–40 °C to +85 °C), VFBGA-48 package compatibility, MoBL® low-power architecture, and pin compatibility with CY62126EV30 for drop-in migration in space-constrained designs.

Technical Context

The device implements a synchronous 64K × 16 SRAM array with dual-byte enable (BHE/BLE) for independent high/low word access, CE-controlled automatic power-down, and CMOS-compatible input/output thresholds. Its timing architecture supports address-controlled and OE-controlled read cycles with guaranteed tAA ≤ 70 ns and tDOE ≤ 35 ns.

It operates exclusively in a single-supply 1.65–1.95 V range with no external voltage translation required, and uses complementary metal oxide semiconductor (CMOS) process technology to achieve sub-2 mA typical active current at 1 MHz while maintaining full-speed operation across the industrial temperature range.

FAQ

Is CY62126EV18LL-70BVXI compatible with 1.8 V I/O standards without level shifters?

Yes. The device operates natively from 1.65 V to 1.95 V and specifies VIH(min) = 1.4 V and VIL(max) = 0.4 V at VCC = 1.8 V, ensuring full compatibility with standard 1.8 V CMOS logic families without external voltage translation circuitry.

What happens to I/O pins during standby mode?

When CE is HIGH, all I/O pins (I/O0–I/O15) enter a high-impedance state regardless of OE, BHE, or BLE status. This prevents bus contention and eliminates loading on external data lines during power-down, simplifying system-level power sequencing.

Does the device support partial-word writes without read-modify-write cycles?

Yes. Independent BHE and BLE inputs allow selective activation of high-byte (I/O8–I/O15) or low-byte (I/O0–I/O7) paths during write operations. This enables true 8-bit writes to either half of the 16-bit word without accessing or modifying the other byte.

Can CY62126EV18LL-70BVXI be used in automotive applications beyond AEC-Q200?

No. While rated for industrial temperature (–40 °C to +85 °C), this device is not AEC-Q200 qualified. For automotive applications requiring qualification, Infineon's automotive-grade SRAM portfolio (e.g., CY62167EV30 series) must be selected instead.
