Description
DS2430AP is a Dallas/Maxim 1-Wire memory IC. It provides 128 bytes (1 Kbit) of non-volatile EEPROM accessible over a single 1-Wire data line (plus ground). Each device has a 64-bit unique ROM ID used to address it on a bus with multiple devices. It can be powered parasitically from the 1‑Wire line or from a separate supply, typically with a pull-up on the bus. Memory is read and written using standard 1-Wire commands (Read Memory; Write/Copy sequences). Common uses include storing small configuration data, calibration constants, device IDs, and simple logs in embedded systems. Widely supported by 1-Wire libraries and compatible with many microcontrollers.
Features
DS2430AP features (concise):
- 1-Kbit (128-byte) nonvolatile EEPROM memory accessible via 1-Wire
- 64-bit unique ROM serial number for device identification
- Fully 1-Wire compliant: supports standard ROM commands (Read ROM, Match ROM, Skip ROM, Search ROM) and memory access
- Parasitic-power capable (bus-powered) with option for an external supply; requires a strong pull-up during writes
- 8-bit CRC for data integrity
- Data retention suitable for embedded applications (endurance typical of NV memory)
- Industrial temperature range (commonly -40°C to +85°C)
- Available in iButton/DS-style packaging suitable for rugged, low-pin-count use
Typical uses: asset tracking, identification, data logging, access control.

Pinout
- Pin count: 3 pins (TO-92/3-lead package)
- Function: 1-Wire 64-bit programmable EEPROM memory. It uses the DQ line for data and can be parasitically powered from DQ; pins are typically GND, DQ, and VDD. Stores 8 bytes (64 bits) of user data plus the device ROM.
