Description
The 25L4005AMC is a CMOS 4,194,304 bit serial Flash memory, which is configured as 524,288 x 8 internally. It features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by CS# input. The 25L4005AMC provides sequential read operation on the whole chip.
Specifications and Features
GENERAL CHARACTERISTICS:
• Serial Peripheral Interface (SPI) compatible - Mode 0 and Mode 3
• 4,194,304 x 1 bit structure
• 128 Equal Sectors with 4K byte each - Any Sector can be erased individually
• 8 Equal Blocks with 64K byte each - Any Block can be erased individually
• Single Power Supply Operation - 2.7 to 3.6 volt for read, erase, and program operations
• Latch-up protected to 100mA from -1V to Vcc +1V
• Low Vcc write inhibit is from 1.5V to 2.5VPERFORMANCE:
• High Performance
- Fast access time: 85MHz serial clock (15pF + 1TTL Load) and 66MHz serial clock (30pF + 1TTL Load)
- Fast program time: 1.4ms(typ.) and 5ms(max.)/page (256-byte per page)
- Fast erase time: 60ms(typ.) and 120ms(max.)/sector (4K-byte per sector); 1s(typ.) and 2s(max.)/block (64K-byte per block)
• Low Power Consumption
- Low active read current: 12mA(max.) at 85MHz, 8mA(max.) at 66MHz and 4mA(max.) at 33MHz
