Infineon Technologies CY62137FV30LL-45ZSXA

Overview

CY62137FV30LL-45ZSXA from Cypress Semiconductor is a 2-Mbit (128 K × 16) MoBL® Automotive CMOS static RAM with 45 ns access time, 2.2 V–3.6 V supply voltage, and –40 °C to +85 °C operating range (Automotive-A grade). It features byte power down, automatic power-down on deselect, and ultra-low standby current (1 µA typical). Used in automotive infotainment head units for temporary display buffer storage.

For engineers reviewing the CY62137FV30LL-45ZSXA datasheet, CY62137FV30LL-45ZSXA pinout, CY62137FV30LL-45ZSXA application, or CY62137FV30LL-45ZSXA equivalent, key selection criteria include automotive temperature compliance, 16-bit bus interface timing, low-voltage standby current, and TSOP II package compatibility with legacy CY62137 family designs.

Technical Context

This SRAM implements a full CMOS architecture with independent byte enable (BHE/BLE) control, enabling selective 8-bit writes to upper or lower data bytes without affecting adjacent memory locations. Its automatic power-down logic activates when CE is HIGH or both BHE and BLE are HIGH, reducing ICC to ≤5 µA.

The device supports three distinct operational modes: active read (CE/OE LOW, WE HIGH), active write (CE/WE LOW, BHE or BLE LOW), and standby (CE HIGH or BHE/BLE HIGH), with guaranteed 45 ns tRC and 22 ns tDOE at VCC = 3.0 V and TA = 25 °C.

FAQ

What is the maximum clock frequency supported by CY62137FV30LL-45ZSXA?

CY62137FV30LL-45ZSXA is an asynchronous SRAM and does not use a clock signal. Its maximum operational speed is defined by access time: 45 ns read cycle time (tRC) and 45 ns write cycle time (tWC) under Automotive-A conditions. System timing depends on external controller's ability to meet setup/hold requirements relative to CE, OE, WE, and address transitions-not a clock frequency.

Does CY62137FV30LL-45ZSXA support data retention at 1.5 V?

Yes. The device guarantees data retention at VCC ≥ 1.5 V with ICCDR ≤ 4 µA (Automotive-A grade). This enables use with supercapacitor or coin-cell backup during main power loss, maintaining stored configuration or fault logs for up to 10 years when combined with its 1 µA typical standby current.

Can CY62137FV30LL-45ZSXA operate reliably during automotive cold-cranking?

Yes. With a minimum operating voltage of 2.2 V and validated operation down to –40 °C, it meets ISO 16750-2 cold-cranking profiles where battery voltage may dip to 6 V (≈2.2 V at 3.3 V regulator output). Its 45 ns timing remains guaranteed across the full –40 °C to +85 °C range without derating.

Is the TSOP II package of CY62137FV30LL-45ZSXA RoHS and AEC-Q100 compliant?

Yes. The CY62137FV30LL-45ZSXA carries full AEC-Q100 Grade 2 qualification (–40 °C to +85 °C) and is RoHS-compliant (lead-free, halogen-free). The TSOP II package uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), requiring bake prior to reflow if exposed >168 hours at <30 °C/60% RH.
