Product details
Overview
R1LV1616RBG-7SR#B0 from Renesas Electronics is a 16Mb low-power static RAM organized as 1M × 16-bit or 2M × 8-bit, fabricated in 0.15µm CMOS, operating from 2.7–3.6V with 70ns access time and 2µA standby current at 3.0V. It supports battery backup operation and TTL-compatible interfacing, and is used in portable instrumentation, industrial controllers, and embedded systems requiring non-refresh, low-voltage memory.
For engineers reviewing the R1LV1616RBG-7SR#B0 datasheet, R1LV1616RBG-7SR#B0 pinout, R1LV1616RBG-7SR#B0 application, or R1LV1616RBG-7SR#B0 equivalent, key selection criteria include its 70ns read access time, µTSOP-52 package with 0.4mm pitch, byte-select capability (LB#/UB#), data retention down to 2.0V, and compatibility with simple parallel bus interfaces without clocks or refresh circuitry.
Technical Context
The R1LV1616RBG-7SR#B0 implements a fully static memory architecture with no internal refresh, relying on external address and control signals (CS1#, CS2, WE#, OE#, LB#, UB#) for read/write operations. Its dual-word/byte organization enables flexible memory mapping via BYTE# input, supported only in TSOP and µTSOP packages.
It features three-state bidirectional I/Os with OR-tie capability, TTL-compatible voltage thresholds (VIH = 2.4V, VIL = 0.4V), and multiple data retention modes triggered by CS1#, CS2, or LB#/UB# assertion-each with defined tCDR and tR timing parameters and IccDR ≤25µA at +70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16Mb (1,048,576 × 16-bit or 2,097,152 × 8-bit) |
| Access Time | 70ns maximum - guarantees valid data within 70ns after address and CS1# stabilization |
| Supply Voltage | 2.7–3.6V - supports single-supply battery-powered systems with brown-out tolerance |
| Standby Current | 2µA typical at 3.0V - enables multi-year battery life in backup mode |
| Data Retention Voltage | 2.0V minimum - preserves stored data during deep sleep or power-loss events |
| Input Compatibility | TTL-level - interfaces directly with legacy microcontrollers and FPGAs without level shifters |
| Package | 52-pin µTSOP (10.79mm × 10.49mm, 0.4mm pitch) - compact footprint for space-constrained PCBs |
Pinout & Package
Package: 52-pin plastic micro Thin Small Outline Package (µTSOP-II), 10.79mm × 10.49mm body, 0.4mm pin pitch, normal-bend leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 1M-word addressing; A-1 used only in byte mode |
| DQ0–DQ15 | Bidirectional Data I/O | Common data bus for read/write; high-impedance when OE# inactive or during write |
| CS1#, CS2 | Chip Select Inputs | Two-level chip enable: CS1# active-low primary select; CS2 enables address/data buffers and controls retention mode |
| WE#, OE#, LB#, UB# | Control Inputs | Write Enable (active-low), Output Enable (active-low), Lower/Upper Byte Select (active-low) - enable partial-byte writes and prevent bus contention |
| Vcc, Vss | Power Supply | Single 2.7–3.6V supply and ground - no separate I/O or core rails required |
| BYTE# | Mode Select Input | Configures x16/x8 operation; supported only in µTSOP/TSOP packages; requires LB#=UB#=L when asserted low |
Key Features
| Feature | Design Value |
|---|---|
| No refresh required | Eliminates external refresh circuitry and timing overhead - simplifies system design and reduces firmware complexity |
| Low standby current | 2µA typical at 3.0V enables >5-year battery backup in always-on monitoring applications |
| Multiple data retention modes | Three configurable retention entry paths (via CS1#, CS2, or LB#/UB#) with guaranteed 2.0V Vcc hold - supports diverse power-management strategies |
| Byte-wide write capability | Independent LB# and UB# pins allow selective 8-bit writes without disturbing adjacent bytes - improves efficiency in mixed-data-size systems |
| TTL-compatible interface | Direct connection to 3.3V or 5V logic families without level translation - reduces BOM count and layout area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV1616AL-70TQLI | 70ns access, 2.7–3.6V, 52-pin TSOP-I - same speed but larger 12×20mm footprint and 0.5mm pitch | Less suitable for ultra-compact designs; higher board space cost | Select if existing layout uses standard TSOP-I or requires longer lead time availability |
| AS6C1616-70BIN | 70ns access, 2.7–3.6V, 48-pin TSOP-I - lacks BYTE# pin and supports x16-only mode | Cannot perform true x8 byte writes; requires software byte masking | Choose when x8 mode is unused and lower pin count simplifies routing |
Compared with IS61LV1616AL-70TQLI and AS6C1616-70BIN, the R1LV1616RBG-7SR#B0 offers superior board-area efficiency via its 10.79mm × 10.49mm µTSOP-52 package and unique hardware byte-enable flexibility, making it optimal for next-generation portable and space-constrained embedded systems.

FAQ
What is the maximum operating temperature range for the R1LV1616RBG-7SR#B0?
The R1LV1616RBG-7SR#B0 is rated for operation from –40°C to +85°C (industrial temperature grade, denoted by "R" in the ordering code). This range is confirmed in the Ordering Information table on page 2 of the REJ03C0101-0400Z datasheet, and applies to all DC and AC specifications including 70ns access time and 2µA standby current.
Does the R1LV1616RBG-7SR#B0 support x8 mode operation?
Yes, the R1LV1616RBG-7SR#B0 supports x8 mode via the BYTE# pin, which is implemented in its 52-pin µTSOP package. When BYTE# is asserted low, the device operates as 2M × 8-bit with DQ0–DQ7 active for lower byte and DQ8–DQ15 for upper byte - as specified in the Pin Description table (page 4) and Byte Enable timing diagram (page 10).
What is the minimum supply voltage required to retain data in the R1LV1616RBG-7SR#B0?
The R1LV1616RBG-7SR#B0 maintains stored data down to 2.0V (VDR), as specified in the Data Retention Characteristics table (page 15). This value is independent of temperature and applies across the full industrial range (–40°C to +85°C), enabling reliable operation during brown-out conditions or battery discharge.
Can the R1LV1616RBG-7SR#B0 be used without external refresh circuitry?
Yes, the R1LV1616RBG-7SR#B0 is a true static RAM with no refresh requirement. The datasheet explicitly states "No clocks, No refresh" under Features (page 1), and the Block Diagram (page 4) shows no refresh controller or clock generator - confirming fully asynchronous operation dependent only on address and control signal timing.
What package type does the R1LV1616RBG-7SR#B0 use, and is it RoHS compliant?
The R1LV1616RBG-7SR#B0 uses a 52-pin plastic micro Thin Small Outline Package (µTSOP-II) with 0.4mm pitch, 10.79mm × 10.49mm dimensions. While the 2007 datasheet does not explicitly state RoHS status, Renesas Electronics declared full RoHS compliance for all new products starting in 2006, and this part carries the "#B0" suffix - Renesas's standard designation for lead-free, RoHS-compliant packaging per their corporate compliance policy.
