Product details
Overview
R1RP0416DGE-2PI#B0 from Renesas Electronics is a 4-Mbit high-speed CMOS static RAM organized as 256-kword × 16-bit, operating from a single 5.0 V ±10% supply, with 12 ns maximum access time and −40 to +85°C industrial temperature range. It serves as cache or buffer memory in embedded systems requiring wide data bus width and deterministic timing, such as industrial controllers and communication baseband subsystems.
For engineers reviewing the R1RP0416DGE-2PI#B0 datasheet, R1RP0416DGE-2PI#B0 pinout, R1RP0416DGE-2PI#B0 application, or R1RP0416DGE-2PI#B0 equivalent, this page delivers verified specifications, SOJ-44 pin mapping, byte-selectable I/O architecture, TTL-compatible interface behavior, and validated alternative SRAM options for drop-in or functionally aligned replacement scenarios.
Technical Context
This SRAM implements a fully static 6-transistor memory cell array with no clocks or refresh required. Its dual-byte enable (UB#/LB#) architecture enables independent 8-bit writes to upper or lower data lanes without affecting adjacent bytes, supporting efficient partial-word updates in real-time control buffers.
The device uses center-VCC/VSS pinout for improved power distribution and noise immunity. All inputs and outputs are directly TTL-compatible, eliminating level-shifting requirements in legacy 5 V microcontroller or DSP bus interfaces - critical for retrofit designs maintaining signal integrity across long trace runs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (256 kwords × 16 bits) - supports full 16-bit parallel data path without external multiplexing |
| Access Time | 12 ns max - enables direct interfacing with 66 MHz CPU buses without wait states |
| Supply Voltage | 5.0 V ±10% - compatible with standard 5 V logic rails; no auxiliary voltage required |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade deployment in uncontrolled ambient environments |
| Standby Current | 5 mA (CMOS mode) - reduces system-level power during idle cycles in battery-backed or energy-sensitive applications |
| Pin Count & Type | 44-pin SOJ (44P0K) - surface-mount package with gull-wing leads; compatible with standard reflow profiles |
| I/O Interface | TTL-compatible inputs/outputs - eliminates need for bus transceivers when connecting to 5 V microcontrollers or FPGAs |
Pinout & Package
Package: 400-mil 44-pin plastic SOJ (44P0K), center-power pinout configuration with VCC and VSS pins positioned at pins 10 and 11 (top row) and pins 34 and 35 (bottom row) for balanced decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Input | 18-bit address bus supporting full 256-kword addressing; no address multiplexing required |
| I/O1–I/O8 | Lower Byte Data I/O | Bi-directional 8-bit data lane controlled by LB#; isolated from upper byte during partial writes |
| I/O9–I/O16 | Upper Byte Data I/O | Bi-directional 8-bit data lane controlled by UB#; operates independently of lower byte |
| CS# | Chip Select | Active-low global enable; places device in standby (5 mA) when high; required for all operations |
| OE# | Output Enable | Active-low read gate; controls output drivers only - does not affect internal state or power consumption |
| WE# | Write Enable | Active-low write strobe; latches data on rising edge when CS# and byte select are asserted |
| UB#, LB# | Byte Select | Independent active-low enables for upper/lower 8-bit lanes; allows granular 1-, 2-, or 4-byte writes |
| VCC, VSS | Power/Ground | Center-placed dual VCC/VSS pairs minimize IR drop and ground bounce in high-speed burst transfers |
| NC | No Connection | Pin 23 is unconnected; must remain floating - no pull-up/down or routing required |
Key Features
| Feature | Design Value |
|---|---|
| Single 5 V supply operation | Eliminates need for dual-rail regulators or charge pumps - simplifies PCB power delivery and reduces BOM count |
| Equal access and cycle times | Enables predictable worst-case timing analysis; no distinction between read/write cycle overhead |
| Byte-selectable write architecture | Prevents unintended overwrites during partial-word updates - essential for real-time firmware patching or DMA buffer management |
| CMOS standby current (5 mA) | Reduces quiescent power by 87.5% vs. TTL standby (40 mA), extending uptime in always-on industrial gateways |
| Direct TTL compatibility | Guarantees logic-level interoperability with legacy 5 V microcontrollers (e.g., 8051, SH-3, older ARM7TDMI) without level shifters |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 3 V core supply (3.3 V tolerant I/O), 45 ns access, 512-kword × 16-bit density | Requires level translation for 5 V systems; slower timing limits use in >22 MHz bus interfaces | Select only when migrating to 3.3 V architecture and relaxing timing budgets |
| IS61LV25616AL-10TLI | 3.3 V supply only, 10 ns access, same 256-kword × 16-bit organization, TSOP-II package | Not pin-compatible with SOJ-44; requires PCB redesign; lacks industrial −40°C rating (only −25°C min) | Choose for new designs targeting lower power and faster access, accepting layout change and reduced temp range |
Compared with R1RP0416DGE-2PI#B0, CY62167EV30LL-45ZSXI trades speed and voltage compatibility for density and modern process efficiency, while IS61LV25616AL-10TLI offers superior speed and smaller footprint but mandates board revision and sacrifices extended temperature support.

FAQ
What is the maximum operating frequency supported by the R1RP0416DGE-2PI#B0?
The R1RP0416DGE-2PI#B0 does not operate on a clock signal - it is a fully static RAM. Its 12 ns maximum access time supports reliable interfacing with 66 MHz synchronous buses (15 ns period) without wait states. Timing margins must be verified against actual board trace lengths and driver strength using the AC characteristics table in the Renesas datasheet Rev. 1.00.
Is the R1RP0416DGE-2PI#B0 pin-compatible with other devices in the R1RP0416DI Series?
Yes - the R1RP0416DGE-2PI#B0 shares identical 44-pin SOJ (44P0K) pinout and electrical behavior with R1RP0416DGE-2PI and R1RP0416DSB-2PI variants. The "#B0" suffix denotes a specific wafer lot or assembly batch code and does not alter functionality, pin assignment, or timing parameters.
Does the R1RP0416DGE-2PI#B0 support partial-word writes without affecting adjacent bytes?
Yes - the R1RP0416DGE-2PI#B0 implements independent UB# (pins 21–22) and LB# (pins 19–20) controls. Asserting only LB# enables writing to I/O1–I/O8 while preserving I/O9–I/O16 contents, and vice versa. This is confirmed in the Operation Table (page 4) and AC timing diagrams for byte-select write cycles.
What is the meaning of "Center VCC and VSS type pin out" for the R1RP0416DGE-2PI#B0?
"Center VCC and VSS" refers to the physical placement of power pins: VCC at pins 10 and 34, VSS at pins 11 and 35 - symmetrically centered along both long edges of the 44-pin SOJ package. This layout minimizes power delivery impedance and reduces simultaneous switching noise during high-speed I/O transitions.
Can the R1RP0416DGE-2PI#B0 be used in automotive applications?
No - the R1RP0416DGE-2PI#B0 is rated for industrial temperature (−40°C to +85°C) and classified as "Standard" quality grade per Renesas documentation. It is not qualified for automotive use (AEC-Q100), nor approved for safety-critical transportation systems. Automotive applications require explicitly qualified parts such as Renesas' "High Quality" grade SRAMs with extended reliability testing.
