A25L020C Series 2Mbit 3V Serial Flash Memory with 100MHz Uniform 4KB Sectors FEATURES Family of Serial Flash Memories Electronic Signatures - A25L020C: 2M-bit /256K-byte - JEDEC Standard Two-Byte Signature Flexible Sector Architecture with 4KB sectors A25L020C: (3012h) - Sector Erase (4K-bytes) in 150ms (typical) - RES Instruction, One-Byte, Signature, for backward - Block Erase (64K-bytes) in 0.8s (typical) compatibility Page Program (up to 256 Bytes) in 1.5ms (typical) A25L020C (11h) 2.7 to 3.6V Single Supply Voltage Package options SPI Bus Compatible Serial Interface - 8-pin SOP (150/209mil), 8-pin DIP (300mil) or 8-pin USON 100MHz Clock Rate (maximum) (2*3mm) and 8-pin WSON (6*5mm) Advanced Protection Features - All Pb-free (Lead-free) products are RoHS compliant - Software and Hardware Write-Protect - Top/Bottom, Block/Sector Array Protection GENERAL DESCRIPTION The A25L020C is 2M bit Serial Flash Memory, with advanced sectors. Each sector is composed of 16 pages. Each page is write protection mechanisms, accessed by a high speed 256 bytes wide. Thus, the whole memory can be viewed as SPI-compatible bus. consisting of 1024 pages, or 262,144 bytes. The memory can be programmed 1 to 256 bytes at a time, The whole memory can be erased using the Chip Erase using the Page Program instruction. instruction, a block at a time, using Block Erase instruction, or a The memory is organized as 4 blocks, each containing 16 sector at a time, using the Sector Erase instruction.
