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. The following commands, PAGE PROGRAM, SECTOR ERASE, BLOCK ERASE, CHIP ERASE, and WRSR are write instructions for Pm25LV512/010.

Table 1. Instruction Set for the Pm25LV512/010

Instruction Name	Instruction Format	Hex Code	Operation
WREN	0000 0110	06h	Set Write Enable Latch
WRDI	0000 0100	04h	Reset Write Enable Latch
RDSR	0000 0101	05h	Read Status register
WRSR	0000 0001	01h	Write Status Register
READ	0000 0011	03h	Read Data from Memory Arrary
FAST_READ	0000 1011	0Bh	Read Data from Memory at Higher Speed
PG_ PROG	0000 0010	02h	Program Data Into Memory Array
SECTOR_ERASE	1101 0111	D7h	Erase One Sector in Memory Array
BLOCK_ERASE	1101 1000	D8h	Erase One Block in Memory Array
CHIP_ERASE	1100 0111	C7h	Erase Entire Memory Array
RDID	1010 1011	ABh	Read Manufacturer and Product ID

READ PRODUCT ID (RDID): The RDID instruction allows the user to read the manufacturer and product ID of the device. The instruction code is followed by three dummy bytes, each bit being latched-in on Serial Data Input (SI) during the rising edge of Serial Clock (SCK). Then the first manufacturer ID (9Dh) is shifted out on Serial Data Output (SO), followed by the device ID (7Bh = Pm25LV512; 7Ch = Pm25LV010) and the second manufacturer ID (7Fh), each bit been shifted out during the falling edge of Serial Clock (SCK).
