25AA1024-E/SM规格书详情
Description:
The Microchip Technology Inc. 25AA1024/25LC1024 (25XX1024*) is a 1024 Kbit serial EEPROM memory with byte-level and page-level serial EEPROM functions. It also features Page, Sector and Chip erase functions typically associated with Flash-based products. These functions are not required for byte or page write operations. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled by a Chip Select (CS) input.
Features:
• 20 MHz max. Clock Speed
• Byte and Page-level Write Operations:
- 256 byte page
- 6 ms max. write cycle time
- No page or sector erase required
• Low-Power CMOS Technology:
- Max. Write current: 5 mA at 5.5V, 20 MHz
- Read current: 7 mA at 5.5V, 20 MHz
- Standby current: 1μA at 2.5V
(Deep power-down)
• Electronic Signature for Device ID
• Self-Timed Erase and Write Cycles:
- Page Erase (6 ms max.)
- Sector Erase (10 ms max.)
- Chip Erase (10 ms max.)
• Sector Write Protection (32K byte/sector):
- Protect none, 1/4, 1/2 or all of array
• Built-In Write Protection:
- Power-on/off data protection circuitry
- Write enable latch
- Write-protect pin
• High Reliability:
- Endurance: 1M erase/write cycles
• Temperature Ranges Supported:
• Pb-free packages available
- Industrial (I): -40°C to +85°C
- Automotive (E): -40°C to +125°C
