Product details
Overview
PCF8582C-2P/03 from NXP Semiconductors (formerly Philips) is a 256 × 8-bit (2 kbit) I²C-bus EEPROM with on-chip voltage multiplier, fault-tolerant redundant storage coding, and internal write timing control. It operates from 2.5 V to 6.0 V, supports up to 100 kHz I²C clock frequency, and delivers 1,000,000 erase/write cycles at 22 °C - used in industrial control modules for non-volatile parameter storage.
For engineers reviewing the PCF8582C-2P/03 datasheet, PCF8582C-2P/03 pinout, PCF8582C-2P/03 application, or PCF8582C-2P/03 equivalent, key selection criteria include its DIP8 package compatibility, hardware-selectable I²C address (A0–A2), PTC pin configuration for external timing control, and guaranteed 10-year data retention at 55 °C.
Technical Context
The PCF8582C-2P/03 implements an I²C slave interface compliant with standard-speed mode (0–100 kHz), with no fast-mode support. Its internal sequencer handles byte and 8-byte page writes autonomously, using either internal oscillator (7 ms/byte typical) or externally gated timing via PTC pin.
Redundant storage coding enables single-bit error tolerance without external ECC logic. The device integrates power-on reset, no external components for write timing, and supports up to eight devices on one I²C bus via A0/A1/A2 hardware addressing - each with unique 7-bit slave address (1010 A2 A1 A0 R/W).

Equivalent & Alternatives
The following parts are listed as comparable options for similar EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C02C-PU | 2 kbit I²C EEPROM; 1 MHz max clock; no redundant storage coding; 400 kHz fast-mode support | Lacks single-bit error tolerance; higher speed but lower intrinsic reliability for long-term calibration storage | Choose when system requires faster I²C throughput and external ECC or redundancy is implemented in firmware |
| STK12C68-55I | NVSRAM (64 kbit); parallel interface; 55 ns access; battery-backed; no I²C interface | Requires parallel bus and backup battery; offers nanosecond read access but incompatible I/O architecture | Choose only if application demands random-access speed and deterministic read latency - not a drop-in replacement |
Compared with AT24C02C-PU and STK12C68-55I, the PCF8582C-2P/03 provides unique fault-tolerant storage and DIP8 through-hole compatibility for legacy designs, while trading off I²C speed and interface flexibility for enhanced data integrity in infrequently updated configurations.

FAQ
What is the maximum I²C clock frequency supported by the PCF8582C-2P/03?
The PCF8582C-2P/03 supports I²C standard-speed mode only, with a maximum clock frequency of 100 kHz. It does not support fast-mode (400 kHz) or high-speed mode. This limitation is specified in Section 8.1.2 of the datasheet and confirmed by timing parameter tLOW and tHIGH minimum values of 4.7 µs and 4.0 µs respectively - consistent with 100 kHz operation. Systems requiring faster EEPROM access must select alternative parts such as the AT24C02C.
How does the redundant storage coding in the PCF8582C-2P/03 improve reliability?
The PCF8582C-2P/03 uses internal redundant storage coding to detect and correct single-bit errors without host processor involvement. This feature increases effective data reliability compared to conventional EEPROMs by eliminating the need for external error detection logic. The redundancy is implemented at the silicon level and applies to all 256 × 8-bit memory locations - verified in the functional description (Section 8) and feature list (Section 2) of the datasheet.
Can the PCF8582C-2P/03 operate from a 3.3 V supply?
Yes, the PCF8582C-2P/03 operates over a supply voltage range of 2.5 V to 6.0 V, fully supporting 3.3 V nominal systems. At VDD = 3.3 V, typical standby current is ≤3.5 µA and read current is ≤100 µA (interpolated from Table 7). All I²C timing parameters remain valid, and logic thresholds (VIL, VIH) scale proportionally - enabling direct interface with 3.3 V microcontrollers without level shifting.
What is the function of the PTC pin (Pin 7) on the PCF8582C-2P/03?
Pin 7 (PTC) is the Programming Time Control output. During internal write cycles, it drives LOW to indicate active programming. It can also be used to gate the internal timer: pulling PTC LOW after the eighth bit of the word address latches external timing control. Leaving PTC unconnected or tied to VDD enables default internal timing (7 ms/byte). External gating increases standby current and requires careful synchronization per Figure 13.
Is the PCF8582C-2P/03 pin-compatible with other Philips EEPROMs?
Yes, the PCF8582C-2P/03 is pin- and address-compatible with PCF8570, PCF8571, PCF8572, PCA8581, and PCF85102, and pin-compatible (with different address mapping) to PCF85103. This compatibility is explicitly stated in Section 2 (Features) and confirmed by identical pin functions (A0–A2, SDA, SCL, VDD, VSS, PTC) and DIP8 packaging (SOT97-1) across these parts - enabling drop-in replacement in existing designs using those variants.
