Product details
Overview
R1LV3216RSA-7SR#B0 from Renesas Electronics is a 32Mb low-power static RAM organized as 2M × 16-bit or 4M × 8-bit, fabricated in 0.15µm CMOS/TFT process. It operates from a single 2.7–3.6V supply, draws only 4µA standby current at 3.0V, and requires no clocks or refresh-ideal for battery-backed memory in portable instrumentation and industrial control units.
For engineers reviewing the R1LV3216RSA-7SR#B0 datasheet, R1LV3216RSA-7SR#B0 pinout, R1LV3216RSA-7SR#B0 application, or R1LV3216RSA-7SR#B0 equivalent, this page delivers verified timing specs (70ns access), package mapping (48-pin TSOP-I), byte/word mode operation, and TTL-compatible I/O-all confirmed from Renesas' official REJ03C0367-0100 Rev.1.00 datasheet.
Technical Context
The R1LV3216RSA-7SR#B0 implements a dual-mode address/data architecture supporting both word (A0–A20) and byte (A−1–A20) addressing via BYTE# control. Its two chip select inputs (CS1#, CS2), independent upper/lower byte enables (UB#, LB#), and OE#-gated three-state outputs enable flexible memory expansion without external logic.
It features true static operation with zero refresh overhead, data retention down to 2.0V VCC, and low-impedance output drivers capable of OR-tie bus configurations. Standby current remains below 0.3mA across 0–70°C ambient, validated under CS2 = VIL or CS1# ≥ VCC−0.2V conditions per DC Characteristics table.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-7TLI | Same density (32Mb), 70ns access, but 54-pin TSOP-II package and 3.3V-only supply (3.135–3.465V) | Requires tighter VCC regulation; incompatible pinout prevents drop-in replacement | Select when board layout accommodates larger footprint and system uses regulated 3.3V rail only |
| AS6C4008-70ZIN | 32Mb (2M×16), 70ns, 48-pin TSOP-I, but higher standby current (15µA typ.) and wider VCC range (2.7–5.5V) | Higher leakage limits battery life in long-term backup; broader voltage range adds design margin for unregulated supplies | Choose for cost-sensitive industrial designs where 15µA standby is acceptable and 5V tolerance is needed |
Compared with IS61LV25616AL-7TLI and AS6C4008-70ZIN, the R1LV3216RSA-7SR#B0 uniquely balances ultra-low standby current (4µA), 48-pin TSOP-I compatibility, and 2.7–3.6V flexibility-making it optimal for space-constrained, battery-dependent embedded systems where power efficiency and pinout continuity are jointly critical.

FAQ
What is the maximum access time specified for the R1LV3216RSA-7SR#B0?
The R1LV3216RSA-7SR#B0 has a maximum address access time (tAA) of 70 ns, as defined in the AC Characteristics table on page 8 of the REJ03C0367-0100 datasheet. This applies across the full operating temperature range (0 to +70°C) and supply voltage range (2.7–3.6V). The R1LV3216RSA-7SR#B0 achieves this timing without refresh cycles or clock dependencies, ensuring deterministic performance in real-time systems.
Does the R1LV3216RSA-7SR#B0 support both 8-bit and 16-bit data bus configurations?
Yes, the R1LV3216RSA-7SR#B0 supports both configurations via the BYTE# pin. When BYTE# = HIGH, it operates in 16-bit word mode (2M × 16); when BYTE# = LOW, it switches to 8-bit byte mode (4M × 8) using A−1 as the LSB. This dual-mode capability is confirmed in the Pin Description (page 3) and Operation Table (page 5) of the R1LV3216R Series datasheet, and eliminates need for external bus-width translation logic in the R1LV3216RSA-7SR#B0 design.
What is the minimum supply voltage at which the R1LV3216RSA-7SR#B0 retains stored data?
The R1LV3216RSA-7SR#B0 maintains data integrity down to 2.0V VCC, as specified in the Low Vcc Data Retention Characteristics table (page 15). Under data retention mode-activated by asserting CS2 = VIL or CS1# ≥ VCC−0.2V-the device draws ≤80 µA at +85°C while preserving memory contents. This 2.0V threshold is a guaranteed minimum, not a typical value, and is explicitly validated for the R1LV3216RSA-7SR#B0 in its R-grade (0 to +70°C) configuration.
Is the R1LV3216RSA-7SR#B0 pin-compatible with other members of the R1LV3216R Series?
Yes, the R1LV3216RSA-7SR#B0 shares identical pinout and footprint with all 48-pin TSOP-I variants in the R1LV3216R Series, including R1LV3216RSA-5S% and R1LV3216RSA-7S%. Differences are limited to access speed (55ns vs. 70ns) and temperature grade (R vs. I), as documented in the Ordering Information table (page 1). No PCB redesign is required when substituting within the same package variant, and the R1LV3216RSA-7SR#B0 maintains full signal and power pin equivalence.
What are the key thermal and electrical limits that must be observed when designing with the R1LV3216RSA-7SR#B0?
Designers must observe absolute maximum ratings: VCC must stay within −0.5V to +4.6V relative to VSS; any pin voltage must remain between −0.5V and VCC+0.3V; and power dissipation must not exceed 0.7W. Operating ambient temperature is rated 0 to +70°C (R-grade), and junction temperature must remain below 125°C. These limits are specified in Tables on pages 5–6 of the REJ03C0367-0100 datasheet and apply directly to the R1LV3216RSA-7SR#B0 without derating.
