概要

Description

The 23LC1024-E/SN is a 1-Mbit Serial SRAM from Microchip with a SPI interface. It stores 131,072 bytes (8-bit wide) and is organized with 3-byte addressing (A16–A0) to cover the full 1 Mb.
Key points:
- Interface: 4‑wire SPI (CS, SCK, SI, SO) with optional WP and HOLD pins.
- Voltage and temp: typically 2.7–3.6 V; industrial temperature variant (-40°C to +85°C) indicated by the “E” suffix.
- Speed: designed for high-speed SPI operation.
- Package: 8-pin SOIC (SN) package.
- Features: supports byte and page writes, sequential reads, and address auto-increment; data is stored in volatile memory (lost when power is removed).
Typical uses: fast, small data buffers, caches, data logging, and other applications needing quick random access without external addressing lines.
Note: Consult the datasheet for exact opcodes, timing, and pin assignments for your specific package.

Features

Here are the key features of the 23LC1024-E/SN (Microchip):
- 1 Mbit serial SRAM: 128K × 8 organization
- SPI-compatible serial interface (SCK, SI, SO, CS) with WP and HOLD pins for protection and bus control
- 3-byte (24-bit) addressing to access the full memory map
- Read/Write operations with Write Enable (WREN) and automatic write protection
- Page write (typically 32-byte pages) and burst/sequential read/write for fast bulk transfers
- High-speed SPI clock up to about 40 MHz
- Single-supply operation: Vcc = 2.7V to 3.6V
- Low power modes: active, and power-down/standby options
- Extended temperature version: -40°C to +85°C
- 8-pin package (SOIC) with RoHS-compliant options (SN suffix)
Notes: Exact timing, page size, and voltage ranges can vary by revision; consult the specific datasheet for precise figures.

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: A global semiconductor company that designs, manufactures, and sells microcontrollers, memory (including SPI SRAM like the 23LC1024), and analog/ interface products. It is publicly traded (NASDAQ: MCHP) and headquartered in Chandler, Arizona, USA.

Application

- External RAM expansion for microcontrollers via SPI
- Data buffering and scratchpad memory
- Look‑up tables and small caches
- Frame buffers for low‑resolution displays and audio/video buffers
- Consumer electronics (set‑top boxes, printers, digital cameras, audio players)
- Industrial/automotive instrumentation for sensor data logging and DMA buffering
- Networking equipment for packet buffering and buffering-intensive operations
Note: 23LC1024-E/SN provides ~1 Mb of SPI SRAM (2.7–5.5V), ideal for fast, temporary data storage.
