Product details
Overview
R1EX24016ASAS0I#S1 from Renesas Electronics is a 16-kbit (2048 × 8-bit) two-wire serial interface EEPROM with I²C-compatible bus interface, 1.8 V to 5.5 V single-supply operation, and 400 kHz maximum clock frequency. It features 16-byte page write capability, 5 ms typical write cycle time, and operates across −40°C to +85°C for industrial embedded control and sensor calibration storage.
For engineers reviewing the R1EX24016ASAS0I#S1 datasheet, R1EX24016ASAS0I#S1 pinout, R1EX24016ASAS0I#S1 application, or R1EX24016ASAS0I#S1 equivalent, key selection criteria include its SOP-8 package compatibility, WP-enabled hardware write protection, 100-year data retention at 25°C, and support for acknowledge polling during internal write cycles.
Technical Context
This device implements a standard I²C protocol-compliant two-wire serial interface with fixed 4-bit device code "1010", 3-bit hardware-selectable address (A0–A2), and R/W bit control. It uses CMOS process with MNOS memory technology to achieve low-power operation and high reliability.
Internal architecture includes a serial-parallel converter, address generator, X/Y decoders, sense amplifier, and high-voltage generator for programming. Write operations support both byte and page modes (up to 16 bytes per page), with automatic address incrementing and wraparound within page boundaries.

Equivalent & Alternatives
The following parts are listed as comparable options for similar EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T | Same 16 kbit capacity, I²C interface, and SOP-8 package; rated for 1 MHz clock (vs. 400 kHz); 1 million endurance cycles | Supports higher-speed bus arbitration in multi-master systems; slightly lower 1.7 V min VCC | Preferred when host controller requires >400 kHz I²C timing or operates below 1.8 V |
| M95160-DRMN6TP/K | 16 kbit SPI interface (not I²C); 8-pin TSSOP; 20 MHz max clock; 4 mA active current (vs. 3 mA) | Requires dedicated SPI peripheral instead of I²C; incompatible bus protocol and pinout | Select only if system already uses SPI peripherals and board layout accommodates different pin assignment |
Compared with AT24C16D-SSHM-T and M95160-DRMN6TP/K, R1EX24016ASAS0I#S1 offers tighter integration with legacy I²C-based microcontrollers, guaranteed 400 kHz timing compliance, and Renesas' industrial-grade qualification for extended temperature operation - making it optimal for cost-sensitive, space-constrained industrial designs where bus compatibility and long-term reliability are prioritized over peak speed.

FAQ
What is the operating voltage range of the R1EX24016ASAS0I#S1?
The R1EX24016ASAS0I#S1 operates from 1.8 V to 5.5 V, enabling direct interface with 1.8 V, 3.3 V, and 5 V logic families without level translation. This wide range supports mixed-voltage system designs and simplifies power architecture in battery-powered or multi-rail embedded applications. The R1EX24016ASAS0I#S1 maintains full I²C functionality and specified timing across this entire voltage window.
Does the R1EX24016ASAS0I#S1 support page write operations?
Yes, the R1EX24016ASAS0I#S1 supports 16-byte page write mode, allowing up to 16 sequential bytes to be written in a single internal 5 ms cycle. This reduces total programming time compared to byte-by-byte writes and minimizes host MCU intervention. The R1EX24016ASAS0I#S1 automatically increments the lower 4 address bits during page write, with wraparound within the current page boundary.
How does the write protect (WP) pin function on the R1EX24016ASAS0I#S1?
When the WP pin is driven high, the R1EX24016ASAS0I#S1 hardware-protects the upper 8 kbit (addresses 0x800–0xFFF) from write operations while permitting full read access. When WP is low, all 16 kbit are writable. This feature allows secure storage of immutable calibration data in the protected region and dynamic user settings in the unprotected region - a capability confirmed in the R1EX24016ASAS0I#S1 datasheet revision 0.02.
What is the data retention specification for the R1EX24016ASAS0I#S1?
The R1EX24016ASAS0I#S1 guarantees 100 years of data retention at 25°C and 10 years at 85°C, as verified per JEDEC standards. This long-term stability is achieved through MNOS memory cell technology and is critical for applications such as medical device calibration records, automotive ECU configuration, and industrial sensor history logs where data integrity must persist across product lifetimes. The R1EX24016ASAS0I#S1 retains data without power or refresh cycles.
Is the R1EX24016ASAS0I#S1 RoHS compliant and lead-free?
Yes, the R1EX24016ASAS0I#S1 is a lead-free product packaged in an RoHS-compliant SOP-8 (PRSP0008DF-B) housing with Ni/Pd/Au plating. Renesas explicitly states "Lead free products" in the Ordering Information section of the R1EX24016ASAS0I#S1 datasheet (REJ03C0359-0002 Rev.0.02), and the device meets EU RoHS Directive requirements for restricted substances.
