The device is optimized for use in many industrial and commercial applications where lowpower and low-voltage operations are essential. The AT93C86A is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP, and 8-lead TSSOP packages.

Upon receiving a READ instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO. The WRITE cycle is completely selftimed and no separate ERASE cycle is required before WRITE. The WRITE cycle is only enabled when the part is in the ERASE/WRITE ENABLE state. When CS is brought “high” following the initiation of a WRITE cycle, the DO pin outputs the READY/BUSY status of the part. The AT93C86A is available in a 2.7V to 5.5V version.

D7 – D0 D15 – D0 Writes memory location An – A0. Erases all memory locations. Valid only at VCC = 4.5V to 5.5V. D 7 – D0 D15 – D0 Writes all memory locations. Valid when VCC = 4.5V to 5.5V and Disable Register cleared. Disables all programming instructions. The AT93C86A is accessed via a simple and versatile 3-wire serial communication interface. Device operation is controlled by seven instructions issued by the host processor. A valid instruction starts with a rising edge of CS and consists of a Start Bit (logic “1”) followed by the appropriate Op Code and the desired memory address location. READ (READ): The Read (READ) instruction contains the ddress code for the memory location to be read. After the instruction and address are decoded, data from the selected memory location is available at the serial output pin DO. Output data changes are synchronized with the rising edges of serial clock SK. It should be noted that a dummy bit (logic “0”) precedes the 8- or 16-bit data output string. The AT93C86A supports sequential read operations. The device will automatically increment the internal address pointer and clock out the next memory location as long as CS is held high. In this case, the dummy bit (logic “0”) will not be clocked out between memory locations, thus allowing for a continuous stream of data to be read. ERASE/WRITE (EWEN): To assure data integrity, the part automatically goes into the Erase/Write Disable (EWDS) state when power is first applied. An Erase/Write Enable (EWEN) instruction must be executed first before any programming instructions can be carried out. Please note that once in the EWEN state, programming remains enabled until an EWDS instruction is executed or VCC power is removed from the part. ERASE (ERASE): The Erase (ERASE) instruction programs all bits in the specified memory location to the logical “1” state. The self-timed erase cycle starts once the ERASE instruction and address are decoded. The DO pin outputs the READY/BUSY status of the part if CS is brought high after being kept low for a minimum of 250 ns (tCS). A logic “1” at pin DO indicates that the selected memory location has been erased, and the part is ready for another instruction. WRITE (WRITE): The Write (WRITE) instruction contains the 8 or 16 bits of data to be written into the specified memory location. The self-timed programming cycle tWP starts after the last bit of data is received at serial data input pin DI. The DO pin outputs the READY/BUSY status of the part if CS is brought high after being kept low for a minimum of 250 ns (tCS). A logic “0” at DO indicates that programming is still in progress. A logic 5 3408D–SEEPR–04/04 “1” indicates that the memory location at the specified address has been written with the data pattern contained in the instruction and the part is ready for further instructions. A READY/BUSY status cannot be obtained if the CS is brought high after the end of the self-timed programming cycle tWP. ERASE ALL (ERAL): The Erase All (ERAL) instruction programs every bit in the memory array to the logic “1” state and is primarily used for testing purposes. The DO pin outputs the READY/BUSY status of the part if CS is brought high after being kept low for a minimum of 250 ns (tCS). The ERAL instruction is valid only at VCC = 5.0V ± 10%. WRITE ALL (WRAL): The Write All (WRAL) instruction programs all memory locations with the data patterns specified in the instruction. The DO pin outputs the READY/BUSY status of the part if CS is brought high after being kept low for a minimum of 250 ns (tCS). The WRAL instruction is valid only at V CC = 5.0V ± 10%. ERASE/WRITE DISABLE (EWDS): To protect against accidental data disturb, the Erase/Write Disable (EWDS) instruction disables all programming modes and should be executed after all programming operations. The operation of the READ instruction is independent of both the EWEN and EWDS instructions and can be executed at any time. 6 AT93C86A [Preliminary] 3408D–SEEPR–04/04 AT93C86A [Preliminary] Timing Diagrams Synchronous Data Timing Note: 1.
