Product details
Overview
R1LV3216RSA-7SI#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, operating from 2.7V to 3.6V with 70ns access time and 4µA typical standby current at 3.0V - deployed in battery-backed memory subsystems for portable instrumentation and industrial control.
For engineers reviewing the R1LV3216RSA-7SI#B0 datasheet, R1LV3216RSA-7SI#B0 pinout, R1LV3216RSA-7SI#B0 application, or R1LV3216RSA-7SI#B0 equivalent, this page delivers verified package mapping (52-pin µTSOP-II), byte/word mode operation, TTL-compatible I/O, no-refresh architecture, and low-voltage data retention down to 2.0V - all confirmed from Renesas REJ03C0367-0100 Rev.1.00.
Technical Context
This device implements a true static RAM architecture with no clocks or refresh cycles, relying on fully static CMOS latches for data retention. Its dual-mode addressing supports both word (A0–A20) and byte (A−1–A20) configurations, enabled by the BYTE# input and controlled via LB#/UB# signals.
Chip select logic uses active-low CS1# combined with active-high CS2 to enter stand-by or data retention modes; output enable (OE#) prevents bus contention, while three-state outputs support OR-tie bus architectures. Standby current drops to 4µA (typ.) at 3.0V with Vcc ≥ 2.0V enabling data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16 or 4,194,304 × 8) |
| Access Time | 70 ns - defines maximum read latency under worst-case voltage/temperature conditions |
| Supply Voltage Range | 2.7 V to 3.6 V - enables direct interface with 3.3V logic and battery-backed systems |

| Operating Temperature | −40 °C to +85 °C - qualified for extended industrial environments |
| Package | 52-pin µTSOP (II), 10.79 mm × 10.49 mm, 0.4 mm pitch - compact footprint for space-constrained PCBs |
Pinout & Package
Package: 52-pin micro Thin Small Outline Package (µTSOP-II), 10.79 mm × 10.49 mm, 0.4 mm lead pitch, normal-bend leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs (word mode) | Select one of 2M addresses in 16-bit mode; A−1 used in byte mode |
| DQ0–DQ15 | Bi-directional data I/O | Common bus interface supporting 8-bit or 16-bit transfers |
| CS1#, CS2 | Chip select controls | CS1# active-low + CS2 active-high enables memory access; CS2 alone controls retention mode |

FAQ
What is the guaranteed data retention voltage for R1LV3216RSA-7SI#B0?
The R1LV3216RSA-7SI#B0 guarantees data retention down to 2.0V (VDR min), as specified in the Low Vcc Data Retention Characteristics table on page 15 of REJ03C0367-0100. At this voltage, the device maintains stored data in standby mode with ICCDR ≤ 80µA at +85°C. This enables reliable operation during brown-out conditions or battery-backed sleep states without external supervision.
Does R1LV3216RSA-7SI#B0 support both 8-bit and 16-bit data bus configurations?
Yes, the R1LV3216RSA-7SI#B0 supports both configurations via the BYTE# pin. When BYTE# = L, the device operates in byte mode (4M × 8-bit) using A−1 as the LSB; when BYTE# = H, it operates in word mode (2M × 16-bit) using A0–A20. LB# and UB# pins control upper/lower byte selection during writes, and the pin description on page 3 confirms this dual-mode functionality.
What is the maximum operating temperature range for R1LV3216RSA-7SI#B0?
The R1LV3216RSA-7SI#B0 is rated for −40°C to +85°C ambient operation (I-version), as defined in the Ordering Information table on page 1 and confirmed in the Recommended Operating Conditions table on page 6. This extended temperature range qualifies it for industrial control cabinets, automotive under-dash environments, and outdoor instrumentation without derating.
How does chip select logic work on R1LV3216RSA-7SI#B0?
R1LV3216RSA-7SI#B0 uses dual chip select inputs: CS1# (active-low) and CS2 (active-high). Memory access requires CS1# = L and CS2 = H. Standby occurs if CS1# = H or CS2 = L. Data retention mode is entered when CS2 = L (regardless of CS1#), as detailed in the Operation Table (page 5) and Low Vcc Data Retention section (page 15).
Is R1LV3216RSA-7SI#B0 pin-compatible with other members of the R1LV3216R Series?
Yes, the R1LV3216RSA-7SI#B0 shares identical pinout and package (52-pin µTSOP-II) with R1LV3216RSD-5S% and R1LV3216RSD-7S%, as shown in the Pin Arrangement diagram on page 2. All variants use the same 52-pin µTSOP (II) footprint and signal mapping, enabling drop-in replacement across speed grades (55ns/70ns) and temperature versions (I/R) within the same package type.
