The synchronous SDR interface clocks at 166 MHz, and the 3.5 ns access time means the first word is available within two clock edges after the address is latched. ## Supply rails and temperature range The commercial temperature grade (0°C to 70°C) suits indoor networking equipment, test instrumentation, and server memory buffers; for extended-temperature environments a different grade would be required. ## Package and tape-and-reel format Supplied in a 100-lead LQFP (100-TQFP, 14x20 mm body) on Tape & Reel — the reel format is the standard for automated pick-and-place assembly. The surface-mount footprint matches the industry-standard 0.5 mm pitch LQFP land pattern, so no special PCB layout accommodation is needed beyond the usual fan-out for the fine pitch.","metaTitle":"CY7C1347G-166AXCT Infineon SRAM, 4.5Mbit, 166 MHz, 100-TQFP","metaDescription":"Active production Infineon CY7C1347G-166AXCT synchronous SDR SRAM, 4.5Mbit (128K x 36), 166 MHz clock, 3.5 ns access, 3.15V-3.6V, 0°C-70°C, 100-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, SDR","Access Time":"3.5 ns","Memory Size":"4.5Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Active","Clock Frequency":"166 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.15V ~ 3.6V","Base Product Number":"CY7C1347","Memory Organization":"128K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.3325","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/40e42469f6f21657989e5e1776329d70.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1347G-166AXCT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy CY7C1347G-166AXCT and how is it quoted?","answer":"Submit an RFQ for a firm price and lead-time commitment."},{"question":"What is the memory organisation and clock speed of CY7C1347G-166AXCT?","answer":"The SRAM is organised as 128K x 36 bits (4.5 Mbit total) and operates with a 166 MHz clock.
