# AT24CS32-SSHM-T

**Microchip Tech** · Pre-ordered MCUs · SOIC-8

AT24CS32-SSHM-T from Microchip Tech, in a SOIC-8. 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 | A0 | input | Device address input, hard-wired to GND or VCC; internally pulled down to GND if left floating, and Microchip recommends a pull-up resistor of 10 kΩ or less when used. |
| 2 | A1 | input | Device address input, hard-wired to GND or VCC; internally pulled down to GND if left floating, and Microchip recommends a pull-up resistor of 10 kΩ or less when used. |
| 3 | A2 | input | Device address input, hard-wired to GND or VCC; internally pulled down to GND if left floating, and Microchip recommends a pull-up resistor of 10 kΩ or less when used. |
| 4 | GND | power_in | Ground reference for the power supply, which should be connected to the system ground. |
| 5 | SDA | bidirectional | Open-drain serial data input/output that must be pulled high through an external pull-up resistor not exceeding 10 kΩ. |
| 6 | SCL | input | Serial clock input; SDA data is latched on its rising edge and clocked out on its falling edge, and it must be held high when the bus is idle or pulled high externally. |
| 7 | WP | input | Write-protect input: connected to GND allows normal write operations, while connected to VCC inhibits all writes to the protected full array. |
| 8 | VCC | power_in | Device power supply pin supplying the source voltage (1.7 V to 5.5 V); operation at invalid VCC voltages may produce spurious results and should not be attempted. |

## CAD (KiCad official)

- Symbol: `AT24CS32-SSHM-T`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `at24cs32-sshm-t-etched.step` / `at24cs32-sshm-t-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `at24cs32-sshm-t.step` / `at24cs32-sshm-t.glb` are the bare package body.
