常見問題解答

What is HM62256ALP-10?

The HM62256ALP-10 is a 32,768 word x 8-bit high-speed CMOS static random access memory (SRAM) chip manufactured by Hitachi. It is commonly used in various electronic devices and systems for data storage and retrieval purposes.

How Does HM62256ALP-10 Work?

The HM62256ALP-10 works by storing digital data in a non-volatile memory array. It allows random access to any memory location, enabling fast read and write operations. The SRAM chip retains data as long as power is supplied and does not require periodic refresh cycles, making it suitable for applications requiring fast and reliable data storage.

How Many Pins does HM62256ALP-10 have and What are the Functions of the Pinout Configuration?

The HM62256ALP-10 is housed in a 28-pin DIP (Dual Inline Package) or SOP (Small Outline Package) package. The pinout configuration includes:

  • Address Pins (A0-A14): Input pins for memory address selection.
  • Data Pins (Q1-Q8): Bidirectional input/output pins for data transfer.
  • Chip Enable (CE), Output Enable (OE), Write Enable (WE): Control pins for enabling memory access and operations.
  • VCC, GND: Power supply and ground pins.

What are the Pros and Cons of HM62256ALP-10?

Pros:

  • High Speed: Offers fast access times for efficient data retrieval.
  • Non-volatile Storage: Retains data without the need for periodic refresh cycles.
  • Low Power Consumption: Operates with low power, suitable for battery-powered devices.
  • Wide Operating Voltage Range: Supports a wide range of supply voltages for flexibility in different applications.

Cons:

  • Small Storage Capacity: May not be suitable for applications requiring large amounts of data storage.
  • Relatively Large Package Size: The 28-pin DIP or SOP package may take up more space compared to smaller form factor memory chips.

Are There Any Equivalents/Alternatives to HM62256ALP-10 for Recommendation?

Alternative SRAM chips with similar specifications to the HM62256ALP-10 include the CY62256 and CY62256L from Cypress Semiconductor, and the AS6C62256 from Alliance Memory.
