Product details
Overview
PCF85103C-2T/00 from NXP Semiconductors (formerly Philips) is a 256 × 8-bit (2 kbit) I²C-bus EEPROM with on-chip voltage multiplier, 2.5–6.0 V single-supply operation, and fault-tolerant redundant storage architecture. It supports byte and 8-byte page write modes, delivers ≤2.0 mA operating current at 6 V, and targets non-volatile configuration storage in embedded control systems.
For engineers reviewing the PCF85103C-2T/00 datasheet, PCF85103C-2T/00 pinout, PCF85103C-2T/00 application, or PCF85103C-2T/00 equivalent, key selection criteria include I²C address flexibility via A0–A2 hardware pins, 100 kHz bus compatibility, 1 million write cycles at 22 °C, 10-year data retention at 55 °C, and SO8 package suitability for space-constrained PCB layouts.
Technical Context
The PCF85103C-2T/00 implements a serial I²C interface compliant with standard-speed mode only (0–100 kHz), requiring external pull-up resistors on SDA and SCL. Its internal sequencer manages write timing without external components, using an on-chip oscillator to generate the 7 ms typical E/W cycle per byte.
Memory organization is fixed at 256 words × 8 bits, with auto-incrementing word addressing during sequential reads/writes. Device addressing uses a 7-bit slave address (0x50–0x57) formed by hardwired A0–A2 inputs, enabling up to eight devices on one I²C bus - identical to PCF85102C-2 but with distinct base address.

FAQ
What is the I²C slave address range supported by the PCF85103C-2T/00?
The PCF85103C-2T/00 supports eight unique I²C slave addresses (0x50–0x57) determined by the logic states of hardware pins A0, A1, and A2. Each pin tied to VDD (logic 1) or VSS (logic 0) selects one of the eight possible addresses, enabling up to eight devices on a single I²C bus without address conflict. The PCF85103C-2T/00 does not support software-configurable addressing.
Does the PCF85103C-2T/00 require an external high-voltage supply for write operations?
No. The PCF85103C-2T/00 integrates an on-chip voltage multiplier that generates the required programming voltage from the standard 2.5–6.0 V supply rail. This eliminates the need for external high-voltage sources, charge pumps, or dedicated programming circuitry - simplifying design and reducing BOM cost. All write operations execute autonomously after I²C command initiation.
How many write cycles can the PCF85103C-2T/00 endure at industrial temperature range?
The PCF85103C-2T/00 guarantees 100,000 erase/write cycles over the full operating ambient temperature range of −40 °C to +85 °C. At 22 °C, endurance increases to 1,000,000 cycles. This specification reflects real-world stress testing per JEDEC standards and ensures reliable operation in frequently updated configuration storage applications.
Is the PCF85103C-2T/00 pin-compatible with other EEPROMs in the same family?
Yes. The PCF85103C-2T/00 is explicitly documented as pin-compatible with PCF8570, PCF8571, PCF8572, PCA8581, PCF8582, and PCF85102C-2. This allows drop-in replacement in existing designs using those parts, provided I²C address and timing constraints are verified. The SO8 (SOT96-1) footprint matches all listed variants.
What is the maximum I²C clock frequency supported by the PCF85103C-2T/00?
The PCF85103C-2T/00 supports I²C standard-mode operation only, with a maximum clock frequency of 100 kHz. It does not support fast-mode (400 kHz) or high-speed mode. This limitation is inherent to its internal timing architecture and must be accounted for in host controller configuration - attempting faster clocks may result in communication failures or incomplete writes.
