Description:

The Microchip Technology Inc. 93XX86A/B/C devices

are 16K bit low-voltage serial Electrically Erasable

PROMs (EEPROM). Word-selectable devices such as

the 93XX86C are dependent upon external logic

levels driving the ORG pin to set word size. The

93XX86A devices provide dedicated 8-bit memory

organization, while the 93XX86B devices provide

dedicated 16-bit memory organization. A Program

Enable (PE) pin allows the user to write-protect the

entire memory array. Advanced CMOS technology

makes these devices ideal for low-power, nonvolatile

memory applications. The entire 93XX Series is

available in standard packages including 8-lead PDIP

and SOIC, and advanced packaging including 8-lead

MSOP, 6-lead SOT-23, 8-lead 2x3 DFN/TDFN and 8-

lead TSSOP. All packages are Pb-free (Matte Tin)

finish.

93AA86A/B/C, 93LC86A/B/C, 93C86A/B/C 2.0 FUNCTIONAL DESCRIPTION When the ORG pin (93XX86C) is connected to VCC, the (x16) organization is selected. When it is connected to ground, the (x8) organization is selected. Instructions, addresses and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is normally held in a High-Z state except when reading data from the device, or when checking the Ready/ Busy status during a programming operation.
PAGE 7
93AA86A/B/C, 93LC86A/B/C, 93C86A/B/C 2.4 Erase The DO pin indicates the Ready/Busy status of the device if CS is brought high after a minimum of 250 ns low (TCSL). DO at logical ‘0’ indicates that programming is still in progress. DO at logical ‘1’ indicates that the register at the specified address has been erased and the device is ready for another instruction. The ERASE instruction forces all data bits of the specified address to the logical ‘1’ state.
PAGE 8
93AA86A/B/C, 93LC86A/B/C, 93C86A/B/C 2.6 Erase/Write Disable and Enable (EWDS/EWEN) Once the EWEN instruction is executed, programming remains enabled until an EWDS instruction is executed or VCC is removed from the device. The 93XX86A/B/C powers up in the Erase/Write Disable (EWDS) state. All programming modes must be preceded by an Erase/Write Enable (EWEN) instruction.
PAGE 9
3AA86A/B/C, 93LC86A/B/C, 93C86A/B/C 2.8 Write The DO pin indicates the Ready/Busy status of the device, if CS is brought high after a minimum of 250 ns low (TCSL). DO at logical ‘0’ indicates that programming is still in progress. DO at logical ‘1’ indicates that the register at the specified address has been written with the data specified and the device is ready for another instruction.
PAGE 10
93AA86A/B/C, 93LC86A/B/C, 93C86A/B/C 2.9 Write All (WRAL) The DO pin indicates the Ready/Busy status of the device if CS is brought high after a minimum of 250 ns low (TCSL). The Write All (WRAL) instruction will write the entire memory array with the data specified in the command. The self-timed auto-erase and programming cycle is initiated by the rising edge of CLK on the last data bit. Clocking of the CLK pin is not necessary after the device has entered the WRAL cycle.

93AA86A/B/C, 93LC86A/B/C, 93C86A/B/C 3.6 Program Enable (PE) This pin allows the user to enable or disable the ability to write data to the memory array. If the PE pin is tied to VCC, the device can be programmed. If the PE pin is tied to VSS, programming will be inhibited. This pin cannot be floated, it must be tied to VCC or VSS. PE is not available on 93XX86A or 93XX86B. On those devices, programming is always enabled. DS21797L-page 12  2003-2012 Microchip Technology Inc.
