الوصف

نظرة عامة على المنتج

The IS42S32200L-6TL is a 64Mbit (2M x 32-bit x 4 banks) Synchronous DRAM (SDRAM) from ISSI (Integrated Silicon Solution Inc.), operating at 166MHz with CAS Latency 3. This device uses a 3.3V single power supply with an LVTTL interface and is packaged in an 86-pin TSOP-II. The -6 speed grade provides 166MHz clock frequency with 5.4ns access time, suitable for networking, computing, and embedded memory applications.

مقدمة المنتج:IS42S32200L-6TL مقدمة المنتج

The IS42S32200L-6TL is a 64Mbit SDR SDRAM from ISSI organized as 2M x 32-bit with 4 internal banks. Operating at 166MHz (CL3) on a 3.3V supply with an LVTTL interface, it delivers up to 667 MB/s peak bandwidth through its 32-bit wide data bus. The 86-pin TSOP-II package is compatible with many legacy embedded and networking designs. This device is now obsolete but was widely used in networking equipment, printers, and industrial systems requiring wide-bus SDRAM memory.

مبدأ العمل:IS42S32200L-6TL مبدأ العمل

The IS42S32200L-6TL operates as a synchronous DRAM where all operations are referenced to the rising edge of the CLK signal. Read and write accesses are burst-oriented starting at a selected location. An ACTIVE command selects the bank and row, followed by a READ or WRITE command selecting the starting column. The 4 internal banks allow interleaved access: one bank can be precharged while another is being accessed, hiding the precharge latency and providing seamless high-speed operation. Auto Precharge mode initiates a self-timed row precharge at the end of the burst. The Mode Register sets CAS Latency (2 or 3), burst length (1/2/4/8/full page), and burst type (sequential/interleaved). Self Refresh mode retains data with minimal power consumption by internally generating refresh cycles. Auto Refresh requires 4096 cycles every 64ms.
