PMC Pm25LV512/010 SERIAL INTERFACE DESCRIPTION Pm25LV512/010 can be driven by a microcontroller on the SPI bus as shown in Figure 1. The serial communication term definitions are in the following section. MASTER: The device that generates the serial clock. SLAVE: Because the Serial Clock pin (SCK) is always an input, the Pm25LV512/010 always operates as a slave. TRANSMITTER/RECEIVER: The Pm25LV512/010 has separate pins designated for data transmission (SO) and reception (Sl). MSB: The Most Signi

SPI peripheral running in either of the two following modes: Mode 0 = (0, 0) The difference between the two modes, as shown in Mode 3 = (1, 1) Figure 2, is the clock polarity when the bus master is in Stand-by mode and not transfering data: For these two modes, input data is latched in on the - Clock remains at 0 (SCK

PMC Pm25LV512/010 DEVICE OPERATION The Pm25LV512/010 is designed to interface directly with the synchronous serial peripheral interface (SPI) of the 6800 type series of microcontrollers. The Pm25LV512/010 utilizes an 8-bit instruction register. The list of instructions and their operation codes are contained in Table 1. All instructions, addresses, and data are transferred with the MSB first and start with a high- to-low transition. Write is defined as program and/or erase in this specification.

PMC Pm25LV512/010 WRITE ENABLE (WREN): The device will power up in the write disable state when Vcc is applied. All write instructions must therefore be preceded by the WREN instruction. WRITE DISABLE (WRDI): To protect the device against inadvertent writes, the WRDI instruction disables all write commands. The WRDI instruction is independent of the status of the WP# pin. READ STATUS REGISTER (RDSR): The RDSR instruction provides access to the status register. The READY/ BUSY and write enable st

PMC Pm25LV512/010 READ: Reading the Pm25LV512/010 via the SO (Serial Output) pin requires the following sequence. After the CE# line is pulled low to select a device, the READ instruction is transmitted via the Sl line followed by the byte address to be read (Refer to Table 7). Upon completion, any data on the Sl line will be ignored. The data (D7-D0) at the specified address is then shifted out onto the SO line. If only one byte is to be read, the CE# line should be driven high after the data c

PMC Pm25LV512/010 SECTOR_ERASE, BLOCK_ERASE: Before a byte can be reprogrammed, the sector/block which contains the byte must be erased. In order to erase the Pm25LV512/010, two separate instructions must be executed. First, the device must be write enabled via the WREN instruction. Then the SECTOR ERASE or BLOCK ERASE instruction can be executed. Table 8.
