CAT93C86VI-GT3

onsemi · EEPROM · SOIC-8

CAT93C86VI-GT3 from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CS input Chip Select. Active-high; asserts the device to accept an instruction or return status/data. Falling edge initiates the self-timed write/erase cycle.
2 SK input Serial Clock Input. Clocks instructions, addresses, and data on DI on its rising edge; up to 3 MHz at Vcc = 4.5-5.5 V.
3 DI input Serial Data Input. Receives start bit, opcode, address and (for WRITE/WRAL) data, sampled on the rising edge of SK.
4 DO tri_state Serial Data Output. High-impedance except when shifting read data or reporting ready/busy status after a write. May be tied to DI to form a common I/O.
5 GND power_in Ground reference (0 V) for the device.
6 ORG input Memory Organization select. Tied to Vcc selects x16 (1024x16) organization; tied to GND selects x8 (2048x8). If left floating an internal pull-up selects x16.
7 PE input Program Enable. PE = 1 required for WRITE, ERASE, WRAL and ERAL instructions; if left floating device is in Program Enabled mode. Don't-care for EWEN/EWDS.
8 VCC power_in Positive supply, 1.8 V to 5.5 V. Icc(write) max 3 mA, Icc(read) max 500 uA, standby Isb typ 0 uA / max 10 uA.
