FUNCTIONAL DESCRIPTION   THE CY62256 IS A HIGH-PERFORMANCE CMOS STATIC RAM ORGANIZED AS 32K WORDS BY 8 BITS. EASY MEMORY EXPANSION IS PROVIDED BY AN ACTIVE LOW CHIP ENABLE (CE ) AND ACTIVE LOW OUTPUT ENABLE (OE ) AND TRI-STATE DRIVERS. THIS DEVICE HAS AN AUTOMATIC POWER-DOWN FEATURE, REDUCING THE POWER CONSUMPTION BY 99.9% WHEN DESELECTED.   AN ACTIVE LOW WRITE ENABLE SIGNAL (WE ) CONTROLS THE WRITING/READING OPERATION OF THE MEMORY. WHEN CE AND WE INPUTS ARE BOTH LOW, DATA ON THE EIGHT DATA INPUT/OUTPUT PINS (I/O 0 THROUGH I/O 7) IS WRITTEN INTO THE MEMORY LOCATION ADDRESSED BY THE ADDRESS PRESENT ON THE ADDRESS PINS (A 0 THROUGH A 14).   READING THE DEVICE IS ACCOMPLISHED BY SELECTING THE DEVICE AND ENABLING THE OUTPUTS, CE AND OE ACTIVE LOW,  WE REMAINS INACTIVE OR HIGH. UNDER THESE CONDITIONS, THE CONTENTS OF THE LOCATION ADDRESSED BY THE INFORMATION ON ADDRESS PINS ARE PRESENT ON TH E EIGHT DATA INPUT/OUTPUT PINS.   THE INPUT/OUTPUT PINS REMAIN IN A HIGH-IMPEDANCE STATE UNLESS THE CHIP IS SELECTED, OUTPUTS ARE ENABLED, AND WRITE ENABLE (WE ) IS HIGH   CATEGORIA DE PRODUTO: SRAM ROHS:   TAMANHO DA MEMÓRIA: 256 KBIT ORGANIZAÇÃO: 32 K X 8 TEMPO DE ACESSO: 70 NS TIPO DE INTERFACE: PARALLEL TENSÃO DE ALIMENTAÇÃO - MÁX: 5.5 V TENSÃO DE ALIMENTAÇÃO - MÍN: 4.5 V TENSÃO DE ALIMENTAÇÃO - MÁX: 50 MA TEMPERATURA OPERACIONAL MÍNIMA: 0 C TEMPERATURA OPERACIONAL MÁXIMA: 70 C ESTILO DE MONTAGEM: SMD/SMT CAIXA / GABINETE: SOIC-28 EMBALAGEM: TUBE MARCA: CYPRESS SEMICONDUCTOR TAXA DE DADOS: SDR TIPO DE MEMÓRIA: SDR SENSÍVEL À UMIDADE: YES NÚMERO DE PORTAS: 1 TIPO DE PRODUTO: SRAM SÉRIE: CY62256NLL CY62256LL-70SNXC HIGH PERFORMANCE CMOS 256K 32K X 8 STATIC RAM MAIORES DETALHES DE CY62256LL-70SNXC NO SITE DO FABRICANTE: HTTPS://PDF1.ALLDATASHEET.COM/DATASHEET-PDF/VIEW/200257/CYPRESS/CY62256LL-70SNXC TAGS DE CY62256LL-70SNXC: CY62256LL-70SNXC, CY62256LL-, CY62256LL, CY62256LL-70NLL, CY62138FLL-45SXI, CY62256NLL-70SNXCT, CI 62256, IC 62256, MEMORIA 256KB, SDRAM 256KB, CY62256
