24C02N

XBLW 24C02N XBLW · EEPROM · DIP-8

24C02N from XBLW 24C02N XBLW, in a DIP-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 A0 input Device/chip-select address input bit 0. Hardwired to VIH or VIL to set the low bit of the 3-bit slave address (device address bits 5-7 of the I2C address byte). Recommended pull-up/pull-down resistor 10 kohm or less; internally interpreted as VIL if left floating but external tie is strongly recommended.
2 A1 input Device/chip-select address input bit 1. Hardwired to VIH or VIL to set the middle bit of the 3-bit slave address. Recommended pull-up/pull-down resistor 10 kohm or less.
3 A2 input Device/chip-select address input bit 2. Hardwired to VIH or VIL to set the high bit of the 3-bit slave address. Together A2/A1/A0 allow up to eight 24C02 devices to share one I2C bus.
4 GND power_in Ground reference (0 V) for the device.
5 SDA bidirectional Serial data line for the two-wire (I2C-compatible) bus. Bidirectional, open-drain output; requires an external pull-up resistor to VCC. Data may only change when SCL is low; SDA transitions while SCL is high are interpreted as START or STOP conditions.
6 SCL input Serial clock input for the two-wire bus. Rising edge latches data into the EEPROM; falling edge clocks data out. Supports 1 MHz at 2.5-5V and 400 kHz at 1.8V. Requires an external pull-up on the bus.
7 WP input Write-protect input. Tied to VIL (or left floating - internally read as VIL, but tie is recommended) allows all programming operations; tied to VIH or VCC disables all write operations while still allowing reads. Recommended pull-up/pull-down resistor 10 kohm or less.
8 VCC power_in Positive supply. Operating range 1.8 V to 5.5 V (industrial temperature -40 to +85 C). Absolute maximum 8 V; any input must stay within -0.3 V to VCC + 0.3 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
24c02n.step 271 KB You want the bare part, or you mark your own boards.
24c02n-etched.step 1.5 MB You want the part with 24C02N already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 368 faces against 148 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
