Infineon Technologies CY62136EV30LL-45ZSXI

Overview

CY62136EV30LL-45ZSXI 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 (max 7 µA). It supports byte-wide write control via BHE/ BLE, automatic power-down on deselect, and operates across –40°C to +85°C for industrial embedded systems.

For engineers reviewing the CY62136EV30LL-45ZSXI datasheet, CY62136EV30LL-45ZSXI pinout, CY62136EV30LL-45ZSXI application, or CY62136EV30LL-45ZSXI equivalent, key selection criteria include VFBGA-48 vs. TSOP II-44 package compatibility, MoBL® low-power timing behavior, CE/OE/BHE/ BLE control logic, and data retention down to 1.0 V.

Technical Context

This SRAM implements a synchronous, non-volatile-retentive memory array organized as 128K words × 16 bits, with independent high- and low-byte enable (BHE/ BLE) for partial-word writes. All control inputs-CE, OE, WE, BHE, BLE-use CMOS-compatible thresholds and support tri-state I/O0–I/O15 during deselect or disable.

It features dual power-down modes: ISB1/ISB2 (≤7 µA at VCC = 3.6 V) triggered by CE HIGH and stable address bus, plus ICCDR ≤3 µA at VCC = 1.0 V for extended data retention. Timing is fully specified at 45 ns cycle time with tDOE = 22 ns and tHZOE = 18 ns.

FAQ

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

Data retention is guaranteed down to VCC = 1.0 V when CE is held HIGH and inputs are at valid CMOS levels. At this voltage, ICCDR remains ≤3 µA, enabling long-term storage during battery backup or brown-out conditions without external capacitors or supercaps.

Does CY62136EV30LL-45ZSXI support true 8-bit write operations?

Yes-via independent Byte High Enable (BHE) and Byte Low Enable (BLE) inputs. When only BLE is LOW, I/O0–I/O7 are written; when only BHE is LOW, I/O8–I/O15 are written. This eliminates need for external byte masking logic or software bit-banding.

Can CY62136EV30LL-45ZSXI be used with a 2.5 V microcontroller without level shifters?

Yes-the device accepts VIH ≥ 1.8 V (at VCC = 2.2–2.7 V) and VIL ≤ 0.6 V, matching standard 2.5 V CMOS logic thresholds. Its 2.2–3.6 V supply range allows direct connection to 2.5 V I/O domains without translation circuitry.

What is the thermal resistance of the 48-ball VFBGA package?

The 48-ball VFBGA package has ΘJA = 54 °C/W (junction-to-ambient, still air, on 4-layer PCB) and ΘJC = 12 °C/W (junction-to-case), enabling reliable operation up to +85°C ambient without forced airflow in typical embedded enclosures.
