AT25QL128A-MHE-T

Adesto Technologies · NOR FLASH · UDFN-8-EP(5x6)

AT25QL128A-MHE-T from Adesto Technologies, in a UDFN-8-EP(5x6). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CS input Chip Select is active low: driving it low enables the device, and when it is high the device is deselected with serial outputs in high impedance; a falling edge is required after power-up before any instruction.
2 SO (IO1) bidirectional Serial Output shifts data out on the falling edge of SCK and is high-impedance when CS is deasserted; it becomes IO1 in Dual/Quad modes.
3 WP (IO2) bidirectional Write Protect is active low and protects the Status Register together with the BP and SRP bits, but it is unavailable as a WP function when QE is set to 1 because the pin then serves as IO2.
4 GND power_in GND is the ground reference for the VCC supply and should be connected to the system ground.
5 SI (IO0) bidirectional Serial Input latches data and commands on the rising edge of SCK and is ignored when the device is deselected; it becomes IO0 in Dual/Quad modes.
6 SCK input Serial Clock provides the interface timing, with data latched on its rising edge and shifted out on its falling edge, supporting up to 133 MHz.
7 HOLD (IO3) bidirectional HOLD is active low and pauses serial communication without deselecting or resetting the device when CS is asserted and SCK is low, and it is internally pulled high and should be tied to VCC whenever possible.
8 VCC power_in VCC is the single supply for all device functions and operates from 1.7 V to 2.0 V; operation at invalid VCC voltages may produce spurious results.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
