... SUMMARY DESCRIPTION The M45PE20 is a 2Mbit (256K x 8 bit) Serial Paged Flash Memory accessed by a high speed SPI-compatible bus. The memory can be written or programmed 1 to 256 bytes at a time, using the Page Write or Page Program instruction. The Page Write instruction consists of an integrated Page Erase cycle fol- lowed by a Page Program cycle ...

... M45PE20 SIGNAL DESCRIPTION Serial Data Output (Q). This output signal is used to transfer data serially out of the device. Data is shifted out on the falling edge of Serial Clock (C). Serial Data Input (D). This input signal is used to transfer data serially into the device. It receives in- structions, addresses, and the data to be pro- grammed ...

... M45PE20 OPERATING FEATURES Sharing the Overhead of Modifying Data To write or program one (or more) data bytes, two instructions are required: Write Enable (WREN), which is one byte, and a Page Write (PW) or Page Program (PP) sequence, which consists of four bytes plus data. This is followed by the internal cy- ...
Page 9
... The environments where non-volatile memory de- vices are used can be very noisy. No SPI device can operate correctly in the presence of excessive noise. To help combat this, the M45PE20 features the following data protection mechanisms: Power On Reset and an internal timer (t can provide protection against inadvertant changes while the power supply is outside the operating specification ...

... M45PE20 MEMORY ORGANIZATION The memory is organized as: 1024 pages (256 bytes each). 262,144 bytes (8 bits each) 4 sectors (512 Kbits, 65536 bytes each) Each page can be individually: – programmed (bits are programmed from – erased (bits are erased from – written (bits are changed to either Figure 6 ...
