1K-BIT SERIAL EEPROM WITH MICROWIRE INTEFACE
(compatible to САТ93С46 Catalyst)
DESCRIPTION
The IN93LC46 is a Electric erasable programmable ROM (EEPROM) memory data capac-
ity 1K (128x8 or 64x16) with 3-wire interface.
There are 3 modification of ICs
A: ICs IN93AA(LC)46AD/AN are 8 bits registers (128х8) - ORG pin is not used
B: ICs IN93AA(LC)46BD/BN are 16 bits registers (64х16) - ORG pin is not used
C: ICs IN93AA(LC)46CN/CD are configured as either registers of 8 bits (ORG pin at GND)
or 16 bits (ORG pin at VCC, or not connected). Each register can be written (or read) seri-
ally by using the DI (or DO) pin.
The ICs is purposed for reading, writing & nonvolatile data storage in electronic units with
3-wire interface. ICs can be used in TV-sets, telecom equipment & consumer electronic
devices.

Note
* this pin is present only in IN93AA46CN, IN93AA46CD:
When the ORG pin is connected to VCC, the x16 organization is selected.
When it is connected to ground, the x8 pin is selected.
If the ORG pin is left unconnected, then an internal pullup device will select the x16 organization.

1) The maximum constant voltage is Ucc+0,5В. While operation pulses up to UCC+2V can be applied to
inputs, pulse duration have to be less than 20 nanoseconds. The maximal constant input voltage is
Ucc+0,5В. While operation positive pulses up to Ucc +2V can be applied to inputs, pulse duration have to
be less than 20 nanoseconds.
2) The minimal constant voltage is -0,5В. While operation negative pulses up to-2V can be applied to
inputs, pulse duration have to be less than 20 nanoseconds. The maximal constant input voltage is
Ucc+0,5В. While operation positive pulses up to Ucc +2V can be applied to inputs, pulse duration have to
be less than 20 nanoseconds.
3) Time no more than 1 sec
