24LC32 Pinout
24LC32 I²C EEPROM · 32-kbit (4KB) I²C serial EEPROM — same DIP-8 pinout as the rest of the 24LCxx family.
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | Input | I²C address bit 0 |
| 2 | A1 | Input | I²C address bit 1 |
| 3 | A2 | Input | I²C address bit 2 |
| 4 | VSS · GND | GND | Ground |
| 5 | SDA | I/O | I²C serial data (needs pull-up) |
| 6 | SCL | Input | I²C serial clock (needs pull-up) |
| 7 | WP | Control | Write protect (high = read-only) |
| 8 | VCC | Power | Supply + (2.5–5.5V) |
How to read the 24LC32 pinout
- 01
Find pin 1
One end of the chip has a half-circle notch or a dot; with the notch facing up, the top-left pin is pin 1.
- 02
Count counter-clockwise
Count counter-clockwise from pin 1: go down the left side first, then up the right side from the bottom.
- 03
Check the table below
Look up each pin's function by number in the table below; power/ground are color-coded, and alternate-function signals are in parentheses.
Frequently asked questions
Where do I usually see a 24LC32?
On many DS3231 real-time-clock modules, which include a 24LC32 (often at 0x57) for general-purpose storage alongside the RTC.
Is it pin-compatible with bigger EEPROMs?
Yes — same DIP-8 pinout as the 24LC64/24LC256; only capacity and page size differ.
Pinout data comes from Microchip 24LC32 datasheet (standard DIP-8 numbering). Refer to the actual device datasheet as authoritative for the pinout.
