Product details
Overview
RM24EP64C-BSNC-B from Adesto Technologies is a sterilization-tolerant, 64Kbit I²C-compatible serial EEPROM replacement based on CBRAM® resistive memory technology. It operates from 2.7V to 3.6V, supports 100kHz/400kHz I²C bus speeds, delivers 50µs byte write and 1ms page write, and withstands 200kGy gamma/e-beam sterilization - enabling use in implantable medical devices requiring repeated terminal sterilization.
For engineers reviewing the RM24EP64C-BSNC-B datasheet, RM24EP64C-BSNC-B pinout, RM24EP64C-BSNC-B application, or RM24EP64C-BSNC-B equivalent, key selection criteria include sterilization tolerance, ultra-low 60nJ byte-write energy, 32-byte page size, 10-year data retention at 70°C, and dual SOIC/TSSOP package compatibility with legacy EEPROM footprints.
Technical Context
This device implements a slave-only I²C interface with SDA (open-drain) and SCL (input-only) pins, using external E0–E2 address bits to support up to eight devices on one bus. Its internal architecture features a 32-byte page buffer and wrap-around address pointer logic that enforces page-boundary alignment during sequential writes.
Write protection is hardware-controlled via the WP pin, sampled only at STOP condition initiation; no software lock bits exist. The device uses Adesto's proprietary CBRAM® technology - not floating-gate flash or traditional EEPROM - delivering faster write speed, lower energy per byte, and superior radiation tolerance without compromising I²C protocol compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 64Kbit (8KB), organized as 8,192 × 8-bit words - sufficient for firmware patch storage or calibration data in Class III medical implants. |
| I²C clock frequency | Up to 400kHz - enables high-throughput configuration loading in real-time diagnostic systems without bus contention. |
| Byte write time | 50µs max - reduces system latency during critical parameter updates, e.g., sensor offset recalibration mid-procedure. |
| Page size | 32 bytes - matches common microcontroller cache line sizes and simplifies firmware-aligned bulk writes. |
| Write energy per byte | 60nJ - 90% lower than comparable EEPROMs, extending battery life in single-use wireless endoscopes. |
| Sterilization tolerance | 200kGy gamma and e-beam - validated for ≥5 terminal sterilization cycles in reusable surgical instruments. |
| Data retention | 10 years at +70°C - ensures calibration integrity over full product lifecycle in autoclave-exposed monitoring modules. |
| Supply voltage range | 2.7V–3.6V - compatible with standard 3.3V medical SoCs and brown-out tolerant across Li-ion discharge profiles. |
Pinout & Package
RM24EP64C-BSNC-B is supplied in an 8-lead JEDEC SOIC (SN) package, 0.150" wide body, with gull-wing leads. Pin pitch is 1.27mm; package dimensions: 4.9mm × 3.9mm × 1.5mm (max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E0 | LSB of device address | Enables multi-drop I²C bus configuration: combined with E1/E2, selects one of eight devices sharing SDA/SCL lines. |
| E1 | MSB-1 of device address | Used with E0/E2 to form 3-bit chip select; eliminates need for external address decoding logic in compact PCB layouts. |
| E2 | MSB of device address | Allows identical RM24EP64C-BSNC-B units to coexist on same bus - essential for modular medical sensor arrays. |
| GND | Reference ground | Must be connected to system analog/digital ground plane; decoupling capacitor (100nF) required within 5mm of VCC pin. |
| SDA | Bidirectional I²C data | Open-drain output requires external pull-up (2kΩ for 400kHz); shared among all I²C slaves on bus. |
| SCL | I²C clock input | Slave-only timing reference; driven exclusively by master MCU - no internal oscillator or clock generation. |
| WP | Hardware write protect | Pulled high to VCC disables all writes (read-only mode); sampled only at STOP edge - immune to runtime glitches. |
| VCC | Power supply | Accepts 2.7–3.6V; internal reset circuit asserts for 75µs after power-up until VCCI ≥2.4V is reached. |
Key Features
| Feature | Design Value |
|---|---|
| CBRAM® memory technology | Enables 200kGy sterilization tolerance unattainable with silicon-based EEPROM or Flash - critical for FDA 510(k)-cleared implants. |
| 60nJ byte-write energy | Reduces average write power by >90% vs. EEPROM, enabling energy-constrained applications like disposable RF ablation catheters. |
| 1ms full-page write | 4–6× faster than EEPROM equivalents - accelerates field-upgrade of safety-critical device parameters during maintenance cycles. |
| Three-wire address enable (E0–E2) | Eliminates need for dedicated I²C address pins; allows eight identical RM24EP64C-BSNC-B devices on one bus without address conflicts. |
| WP pin sampling at STOP | Prevents partial writes during power interruption - guarantees atomicity of configuration updates in battery-powered portable monitors. |
| Sequential read capability | Reads entire 8KB array in one I²C transaction - simplifies host firmware for diagnostic log retrieval in telemetry-enabled pacemakers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C64D-SSHM-T | Standard EEPROM; 1MHz I²C, 5ms page write, no sterilization rating, 200k write cycles | Lacks 200kGy tolerance; unsuitable for reusable sterilized devices; limited to single-use or non-sterile environments | Select only if sterilization is not required and higher I²C speed justifies slower write performance. |
| M95M02-DRMN6TP/K | 128Kbit SPI EEPROM; 20MHz interface, 5ms page write, 400kGy gamma-rated but no e-beam validation | Requires SPI interface redesign; e-beam tolerance unverified - invalidates use in electron-beam sterilized orthopedic tools | Consider only when migrating to SPI architecture and gamma-only sterilization is confirmed in final device design. |
Compared with AT24C64D-SSHM-T and M95M02-DRMN6TP/K, RM24EP64C-BSNC-B uniquely combines dual sterilization validation, sub-100µs write latency, and I²C compatibility - making it the only drop-in solution for FDA-regulated, multi-cycle sterilizable medical electronics requiring EEPROM footprint equivalence.

FAQ
What sterilization methods and doses is RM24EP64C-BSNC-B qualified for?
RM24EP64C-BSNC-B is validated for both gamma irradiation and e-beam sterilization at 200kGy - the maximum dose used in commercial medical device terminal sterilization. This qualification covers full functionality, data retention, and write endurance after exposure, per ISO 11137. No derating or post-sterilization burn-in is required for RM24EP64C-BSNC-B.
Does RM24EP64C-BSNC-B require changes to existing EEPROM firmware drivers?
No. RM24EP64C-BSNC-B maintains full I²C protocol compatibility with standard EEPROMs, including identical control byte format (1010xxxR/W), address mapping (A0–A12), and ACK/NACK timing. Existing AT24C64 or similar driver stacks work without modification - only WP pin handling differs due to edge-triggered sampling at STOP.
How does the 60nJ byte-write energy of RM24EP64C-BSNC-B translate to system-level power savings?
At 3.3V supply, RM24EP64C-BSNC-B consumes just 18.2nC per byte write (60nJ ÷ 3.3V). Compared to typical EEPROMs drawing 1mA for 5ms (5µC), this represents a 275× reduction in charge transfer - directly extending battery life in single-use devices like RF ablation catheters by measurable hours under continuous logging duty cycles.
Can RM24EP64C-BSNC-B replace legacy EEPROMs in existing SOIC-8 PCB footprints?
Yes. RM24EP64C-BSNC-B uses the JEDEC-standard 8-lead SOIC (SN) package with 1.27mm pitch and 4.9mm × 3.9mm body - identical to AT24C64D-SSHM-T and other industry-standard EEPROMs. No layout revision is needed; only ensure WP pin is pulled high for read-only operation or low for writes, matching existing schematic intent.
What is the endurance specification for RM24EP64C-BSNC-B, and how is it verified?
RM24EP64C-BSNC-B guarantees 10,000 write cycles per memory location, measured per JEDEC Standard JESD22-A117. Endurance testing includes full-page and random-byte stress patterns across temperature (0°C to +70°C) and voltage (2.7V–3.6V), with data retention verified post-cycling. This exceeds typical EEPROM specs and aligns with FDA guidance for Class III device memory longevity.
