Product details
Overview
PCF85102C-2T/03 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 PCF85102C-2T/03 datasheet, PCF85102C-2T/03 pinout, PCF85102C-2T/03 application, or PCF85102C-2T/03 equivalent, this device offers verified I²C standard-mode (≤100 kHz) compatibility, 1 M cycle endurance at 22 °C, 10-year data retention at 55 °C, and SO8 package suitability for space-constrained industrial PCBs.
Technical Context
The PCF85102C-2T/03 implements an I²C slave interface with fixed 7-bit device address (1010xxxR/W), hardware-selectable A0–A2 pins enabling up to eight devices on one bus, and internal sequencer-driven write cycles requiring no external timing components. Its block diagram confirms dedicated I²C bus control logic, 128-divider oscillator, 16-step timer, and 8-byte shift register with auto-incrementing address pointer.
It operates exclusively in I²C standard-speed mode (0–100 kHz), lacks fast-mode support, and uses internal power-on reset and latch-up protection per JEDEC JESD78 (>100 mA). The redundant storage code provides single-bit error tolerance without external ECC overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 256 × 8-bit (2 kbit) non-volatile EEPROM organized as 256 addressable bytes |
| Supply voltage | 2.5 V to 6.0 V - enables direct interfacing with 3.3 V and 5 V microcontrollers without level shifting |
| Write endurance | 1,000,000 erase/write cycles at 22 °C - supports frequent firmware parameter updates in field-deployed equipment |
| Data retention | 10 years at 55 °C - ensures long-term reliability in industrial ambient conditions |
| I²C clock frequency | 0–100 kHz - compliant with I²C standard-mode only; not compatible with fast-mode (400 kHz) or high-speed mode |
| Standby current | ≤10 µA at 6.0 V - minimizes quiescent power in battery-backed or energy-harvesting applications |
| Page write capacity | 8-byte page write - reduces total programming time vs. byte writes; internal auto-increment of low-order address bits |

| A2 | Hardware address input 2 | Configures MSB of I²C slave address; allows up to eight PCF85102C-2T/03 devices on same I²C bus (16 kbit aggregate) |
| VSS | Negative supply (ground) | Reference return path for all internal circuitry; must be connected to system ground plane |
| SDA | Serial data I/O (bidirectional) | Open-drain I²C data line requiring external pull-up resistor; transmits/receives address, command, and data bytes |
| SCL | Serial clock input | Open-drain I²C clock line requiring external pull-up resistor; synchronizes all data transfers on the bus |
| N.C. | No connect | Internally unconnected pin; must remain floating - no routing or termination required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C02C-SSHM-T | 2 kbit I²C EEPROM; 1.7–5.5 V supply; 400 kHz fast-mode support; no redundant storage | Lacks single-bit error tolerance; requires external ECC or CRC for safety-critical use | Preferred where higher I²C speed or lower voltage operation is needed, and redundancy is not required |
| M95020-WMN6TP | 2 kbit SPI EEPROM; 2.5–5.5 V; 20 MHz SPI interface; no I²C compatibility | Uses SPI instead of I²C - requires different MCU peripheral and PCB routing | Select when existing design uses SPI bus or needs faster random access than I²C permits |
Compared with AT24C02C-SSHM-T and M95020-WMN6TP, the PCF85102C-2T/03 uniquely delivers fault-tolerant storage in an I²C interface with proven industrial temperature range and legacy pin/address compatibility - making it optimal for upgrade paths from PCF857x/PCF858x families.

FAQ
What is the maximum I²C clock frequency supported by the PCF85102C-2T/03?
The PCF85102C-2T/03 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 explicitly stated in Section 8.1.2 of the datasheet and confirmed in Table 8 (I²C-bus characteristics), where fSCL max = 100 kHz under all operating conditions. Using higher frequencies may result in communication failure or data corruption.
Does the PCF85102C-2T/03 require an external high-voltage programming supply?
No, the PCF85102C-2T/03 does not require an external high-voltage programming supply. It integrates an on-chip voltage multiplier that generates the necessary programming voltage from the standard 2.5–6.0 V VDD supply. This feature eliminates the need for a separate VPP pin or external charge pump circuit, simplifying board design and reducing component count.
How many PCF85102C-2T/03 devices can share the same I²C bus?
Up to eight PCF85102C-2T/03 devices can share the same I²C bus. This is enabled by three hardware-selectable address inputs (A0, A1, A2), each configurable as logic HIGH or LOW to generate unique 3-bit chip address codes. As shown in Figure 3 and Table 5, these combinations yield eight distinct I²C slave addresses (1010000R/W through 1010111R/W).
What is the data retention specification for the PCF85102C-2T/03 at elevated temperature?
The PCF85102C-2T/03 guarantees 10 years of data retention at an ambient temperature of 55 °C, as specified in Table 7 (Characteristics). At 85 °C, retention time decreases; the datasheet does not specify a minimum value above 55 °C, so system-level testing is recommended for applications operating continuously near the upper temperature limit.
Is the PCF85102C-2T/03 pin-compatible with other members of the PCF85xx family?
Yes, the PCF85102C-2T/03 is pin- and address-compatible with PCF8570, PCF8571, PCF8572, PCA8581, and PCF8582, and pin-compatible (with different address mapping) to PCF85103. This compatibility is explicitly stated in Section 2 (Features) and enables drop-in replacement in legacy designs using those parts, provided address conflicts are resolved via A0–A2 strap configuration.
