常見問題解答

What is LH52256CN-10LL?

The LH52256CN-10LL is a 256K x 8 (2M-bit) static random access memory (SRAM) chip manufactured by Sharp Corporation. It is designed to provide fast and reliable data storage and retrieval in various electronic systems, including embedded control systems, networking equipment, and communication devices.

How Does LH52256CN-10LL Work?

The LH52256CN-10LL works by storing and retrieving digital data in a non-volatile, static fashion. It features a fast access time and low power consumption, making it suitable for applications requiring quick and efficient data access. The SRAM chip retains stored data as long as power is supplied to the device.

How Many Pins does LH52256CN-10LL have and What are the Functions of the Pinout Configuration?

The LH52256CN-10LL is housed in a 28-pin DIP (Dual Inline Package) configuration. The pinout configuration includes:

  • Vcc: Power supply pin.
  • GND: Ground pin.
  • CE1, CE2: Chip enable pins for controlling the device operation.
  • OE: Output enable pin for enabling data output.
  • WE: Write enable pin for controlling write operations.
  • Address Pins (A0-A17): Inputs for specifying the memory address for read or write operations.
  • Data Pins (DQ0-DQ7): Bidirectional data input/output pins.

What are the Pros and Cons of LH52256CN-10LL?

Pros:

  • Fast Access Time: Provides quick data access for high-speed applications.
  • Low Power Consumption: Operates with low power requirements, suitable for battery-powered devices.
  • Non-volatile Storage: Retains data even when power is removed, eliminating the need for constant refresh cycles.
  • Reliability: Offers stable and reliable data storage and retrieval.
  • Wide Temperature Range: Suitable for operation across a wide temperature range, making it versatile for different environments.

Cons:

  • Cost: SRAM chips with large capacities, such as the LH52256CN-10LL, may have higher costs compared to lower-capacity alternatives.
  • Limited Storage Capacity: May not be suitable for applications requiring larger memory capacities.
  • Package Size: The 28-pin DIP package may not be space-efficient for compact designs.

Are There Any Equivalents/Alternatives to LH52256CN-10LL for Recommendation?

  • The CY62256VNLL-70SNXI from Cypress Semiconductor is a similar 256K x 8 SRAM chip with comparable features.
  • Alternative SRAM chips to the LH52256CN-10LL include the AS6C62256A from Alliance Memory and the HM62256BLP-7 from Hitachi.
