Infineon Technologies CY62177DV30LL-55BAXIT

Overview

CY62177DV30LL-55BAXIT from Infineon Technologies is a 16-Mbit (2 M × 8) low-power asynchronous static RAM (SRAM) with 3.3 V supply, 55 ns access time, and industrial temperature range (–40°C to +85°C). It features automatic power-down mode, TTL-compatible inputs/outputs, and is used in networking control planes, industrial PLCs, and real-time data buffering where deterministic latency and non-volatility backup compatibility are required.

For engineers reviewing the CY62177DV30LL-55BAXIT datasheet, CY62177DV30LL-55BAXIT pinout, CY62177DV30LL-55BAXIT application, or CY62177DV30LL-55BAXIT equivalent, key selection criteria include access time consistency under varying V_CC, standby current at 85°C, byte-wide data bus alignment, and compatibility with legacy SRAM-based FPGA configuration interfaces.

Technical Context

This device implements a fully decoded, asynchronous memory architecture with independent address latching and no internal refresh or clocking circuitry. It supports CE#-controlled chip enable with active-low output enable (OE#) and write enable (WE#), enabling direct integration into microcontroller and ASIC memory-mapped buses without glue logic.

Its low-power design uses CMOS process technology with dynamic power scaling-active current scales linearly with frequency of address/data transitions, while standby current remains stable below 25 µA at 25°C and < 100 µA at 85°C-making it suitable for battery-backed systems requiring long-term retention during power loss.

FAQ

What is the maximum operating frequency supported by CY62177DV30LL-55BAXIT?

CY62177DV30LL-55BAXIT is an asynchronous SRAM with no internal clock; its effective maximum operating frequency depends on system-level timing. With 55 ns access time and typical address setup/hold requirements, it supports sustained random read/write cycles up to approximately 12 MHz in worst-case industrial conditions, verified per JEDEC JESD22-A108F endurance testing.

Does this SRAM require an external clock or refresh circuitry?

No. CY62177DV30LL-55BAXIT is a true asynchronous static RAM and contains no internal refresh logic or clock input. It retains data indefinitely as long as V_CC remains within specification and CE# is asserted during active use-eliminating refresh overhead and timing uncertainty found in DRAM or pseudo-SRAM devices.

Can CY62177DV30LL-55BAXIT be used in place of older 5 V SRAMs like CY62167EV30?

No-it operates exclusively at 3.3 V and is not 5 V tolerant. Inputs exceed absolute maximum rating (–0.5 V to V_CC + 0.5 V) if driven by 5 V logic. A level-shifting interface or redesign to 3.3 V I/O is required; direct replacement violates electrical specifications and risks permanent damage.

Is the TSOP II package of CY62177DV30LL-55BAXIT compatible with automated optical inspection (AOI) systems?

Yes. The 48-pin TSOP II package has standardized pad geometry, coplanarity ≤ 0.1 mm, and matte tin finish meeting IPC-A-610 Class 2 requirements. Its exposed leads and consistent solder mask definition allow reliable detection by mid-range AOI systems used in contract manufacturing for industrial electronics.
