HT24C02ARZ

HTCSEMI · EEPROM · SOP-8

HT24C02ARZ from HTCSEMI, in a SOP-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 address input bit 0. Hard-wire to VCC or VSS to set the chip's 2-wire slave address; up to eight HT24C02 devices can share one bus. Floating pin is internally read as VSS (low).
2 A1 input Device address input bit 1. Hard-wire to VCC or VSS to set the chip's 2-wire slave address. Floating pin is internally read as VSS (low).
3 A2 input Device address input bit 2. Hard-wire to VCC or VSS to set the chip's 2-wire slave address. Floating pin is internally read as VSS (low).
4 VSS power_in Negative power supply, ground reference.
5 SDA bidirectional Bidirectional 2-wire serial data. Open-drain output; requires an external pull-up resistor to VCC. Can be wire-OR'd with other open-drain/collector devices.
6 SCL input Serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Max 400 kHz at 1.8-5.0V, up to 1 MHz at 2.5-5.0V.
7 WP input Hardware write protect. Tie to VCC to inhibit writes to the full 2K array (device acts as a serial ROM); tie to VSS or leave floating to allow normal read/write.
8 VCC power_in Positive power supply, 1.8V to 5.5V over -40 to +85 degC. Max 5 mA operating (write at 400 kHz), 3 uA standby.

  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ht24c02arz-etched.step / ht24c02arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht24c02arz.step / ht24c02arz.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: HTCSEMI datasheet (10 pp, sha256 be1286d196ee2c5e, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
