Product details
Overview
R1EV58064BTCRBI#B2 from Renesas Electronics is a 64 Kbit (8-Kword × 8-bit) parallel EEPROM with MONOS memory technology, 100 ns access time at 2.7–4.5 V, Ready/Busy signaling, and RES pin-based hardware write protection. It operates across –40°C to +85°C and supports automatic byte/page programming for embedded control and industrial data logging applications.
For engineers reviewing the R1EV58064BTCRBI#B2 datasheet, R1EV58064BTCRBI#B2 pinout, R1EV58064BTCRBI#B2 application, or R1EV58064BTCRBI#B2 equivalent, key selection factors include TSOP-28 package compatibility, RES-driven power-on write inhibit, 64-byte page write timing (≤10 ms), and JEDEC-compliant byte-wide interface for legacy microcontroller bus integration.
Technical Context
This device implements a parallel byte-wide interface with address latching on CE or WE falling edges and data latching on rising edges. Its internal architecture includes on-chip address/data latches, high-voltage generator, and voltage detector for RES-controlled reset behavior - exclusive to the R-series variant.
The R1EV58064BTCRBI#B2 integrates MONOS nonvolatile memory cells with CMOS peripheral circuitry, enabling 10⁵ erase/write cycles and >10-year data retention. It supports three write protection methods: hardware (RES pin), software (6-byte unlock sequence), and noise immunity (<15 ns pulse rejection on control pins).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 64 Kbit (8,192 × 8-bit), directly maps to 16-bit MCU data bus without external demultiplexing |
| Access time | 100 ns max at 2.7–4.5 V supply - meets timing budgets for 8/16-bit microcontrollers running ≤10 MHz |
| Write cycle time | 10 ms max for byte or 64-byte page - enables deterministic firmware update latency in safety-critical systems |
| Operating voltage | 2.7–5.5 V single supply - interoperable with 3.3 V and 5 V logic families without level translation |
| Data retention | ≥10 years at +85°C - validated for industrial equipment deployed in uncontrolled thermal environments |
| Endurance | 100,000 write/erase cycles - sufficient for daily configuration updates over 27+ years of operation |
| Temperature range | –40°C to +85°C industrial grade - qualified for use in motor drives, PLCs, and metering hardware |
Pinout & Package
28-pin plastic TSOP (PTSA0028ZB-A / TFP-28DBV), 8.0 mm × 11.8 mm footprint, 0.55 mm pitch, lead-free, tray-packaged.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address input | 13-bit address bus supporting full 8-Kword addressing; A6–A12 latched as page address on first WE/CE edge |
| I/O0–I/O7 | Data input/output | Bi-directional 8-bit data bus; I/O6 toggles during write for status monitoring; I/O7 outputs polling bit |
| CE | Chip enable | Active-low chip select; falling edge latches address; must be held stable during write cycle initiation |
| OE | Output enable | Active-low read control; enables output drivers only when CE is active - prevents bus contention |
| WE | Write enable | Active-low write strobe; falling edge latches address; rising edge latches data; controls byte/page mode entry |
| RDY/Busy | Ready/Busy open-drain output | Drives low during internal write; high-impedance otherwise - enables hardware wait-state generation |
| RES | Reset input | Active-low hardware write inhibit; forces high-impedance I/O and blocks programming when pulled low |
| VCC, VSS | Power supply | Single 2.7–5.5 V supply; VSS referenced ground plane required for noise immunity on control lines |
| NC | No connection | Pin 3 is unconnected - must remain floating or tied to VSS per layout guidelines to avoid coupling noise |
Key Features
| Feature | Design Value |
|---|---|
| RES pin hardware protection | Prevents unintended writes during power-up/down by forcing unprogrammable state when RES = VSS |
| 64-byte page write | Reduces firmware update time by 64× vs. byte-write - critical for field-upgradable industrial controllers |
| Data polling & Toggle Bit | Enables software-driven write completion detection without RDY/Busy hardware connection |
| Software data protection | 6-byte unlock sequence (AA/55/80/AA/55/20) prevents accidental writes from corrupted firmware or noise |
| MONOS memory cell | Delivers 10⁵ endurance and >10-year retention without charge-pump wear-out mechanisms of floating-gate EEPROM |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C64B-15PU | 150 ns access time; no RES pin; 5 V only (4.5–5.5 V); 10K endurance cycles | Lacks hardware reset protection and industrial temperature support; suitable only for legacy 5 V designs | Select only if board uses 5 V logic and does not require power-cycle write inhibition |
| FM24CL64B-G | Serial I²C interface; 400 kHz max clock; 3.3 V only; FRAM-based (unlimited endurance) | Requires protocol stack changes; eliminates write latency but adds software complexity | Choose when system already uses I²C and demands infinite write cycles - not a drop-in replacement |
Compared with AT28C64B-15PU and FM24CL64B-G, the R1EV58064BTCRBI#B2 uniquely combines TSOP-28 parallel interface, RES-driven hardware lock, and MONOS reliability - making it optimal for retrofitting legacy 8-bit systems needing robust industrial-grade nonvolatile storage without redesigning bus architecture.

FAQ
What is the function of the RES pin on the R1EV58064BTCRBI#B2?
The RES pin on the R1EV58064BTCRBI#B2 is an active-low hardware reset input that forces the device into an unprogrammable state when pulled low. It disables all read and write operations, preventing unintended writes during power-up/down sequences. The R1EV58064BTCRBI#B2 requires RES to be held low for ≥100 μs after VCC stabilization and high for ≥10 ms after final data input to ensure reliable operation.
Does the R1EV58064BTCRBI#B2 support both byte and page write modes?
Yes, the R1EV58064BTCRBI#B2 supports automatic byte write (≤10 ms) and 64-byte page write (≤10 ms). Page write is initiated by loading up to 64 bytes within 30 μs of each preceding WE or CE falling edge. The R1EV58064BTCRBI#B2 automatically enters write mode after 100 μs of CE or WE high, eliminating need for external timing control.
How does the R1EV58064BTCRBI#B2 indicate write completion?
The R1EV58064BTCRBI#B2 provides two hardware-assisted write completion indicators: the RDY/Busy pin drives low during internal write and returns to high-impedance afterward, and I/O6 toggles during active programming (Toggle Bit). Additionally, I/O7 outputs inverted data during polling - both methods are fully supported in the R1EV58064BTCRBI#B2.
What is the maximum operating voltage and temperature range for the R1EV58064BTCRBI#B2?
The R1EV58064BTCRBI#B2 operates from 2.7 V to 5.5 V DC supply and is rated for –40°C to +85°C ambient temperature. Its MONOS memory cell technology ensures 100,000 write/erase cycles and >10-year data retention across this full industrial temperature range, validated per JEDEC standards.
Is the R1EV58064BTCRBI#B2 pin-compatible with other 28-pin parallel EEPROMs?
The R1EV58064BTCRBI#B2 uses a standard 28-pin TSOP footprint (PTSA0028ZB-A) with JEDEC-compliant pinout, but its RES pin (Pin 27) is unique to the R-series and absent in N-series or legacy EEPROMs like AT28C64B. Direct replacement requires verification of RES signal routing and software handling - it is not a drop-in substitute for non-R-series parts.
