Product details
Overview
R1LV3216RSD-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 R1LV3216RSD-7SI#B0 datasheet, R1LV3216RSD-7SI#B0 pinout, R1LV3216RSD-7SI#B0 application, or R1LV3216RSD-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 critical for embedded SRAM selection in space-constrained, power-sensitive designs.
Technical Context
The R1LV3216RSD-7SI#B0 implements a fully asynchronous, no-clock, no-refresh static RAM architecture with dual chip select (CS1#, CS2), independent upper/lower byte enables (UB#, LB#), and BYTE#-controlled mode switching between word and byte addressing. Its address buffer supports A0–A20 (21 pins) plus A−1 for byte-mode addressing.
It features three-state OR-tie capable outputs, OE#-controlled bus contention prevention, and flexible power management: standby current drops to 4µA (typ) at 3.0V, with guaranteed data retention down to VCC = 2.0V while maintaining ISB1 ≤ 80µA at +85°C - enabling seamless battery backup without external refresh circuitry.

FAQ
What is the operating temperature range for the R1LV3216RSD-7SI#B0?
The R1LV3216RSD-7SI#B0 is rated for industrial temperature operation from −40°C to +85°C, as indicated by the "I" suffix in the part number. This specification is validated per the Recommended Operating Conditions table (Page 6) and Absolute Maximum Ratings (Page 5) of the official Renesas datasheet REJ03C0367-0100. The device maintains full functionality-including 70ns access time and 4µA typical standby current-across this full range.
Does the R1LV3216RSD-7SI#B0 require a clock signal or refresh circuitry?
No, the R1LV3216RSD-7SI#B0 is a true static RAM and requires neither a clock signal nor periodic refresh cycles. Its asynchronous design uses standard control signals (CS1#, CS2, WE#, OE#, LB#, UB#) for read/write operations, as confirmed in the Features section (Page 1) and Operation Table (Page 5) of the datasheet. This eliminates timing controller complexity and guarantees deterministic latency in real-time embedded systems.
How does byte-mode operation work on the R1LV3216RSD-7SI#B0?
Byte-mode operation on the R1LV3216RSD-7SI#B0 is enabled by driving BYTE# low, which activates A−1 as an address bit and configures the device as 4M × 8-bit. In this mode, LB# and UB# independently control DQ0–DQ7 and DQ8–DQ15 respectively. The Operation Table (Page 5) explicitly defines byte write/read sequences, and timing parameters tBS/tBR (Page 10) govern BYTE# setup and recovery. This mode is not available on pin-compatible alternatives like IS61WV3216EDBLL-70BLI.
What is the minimum supply voltage required to retain data in the R1LV3216RSD-7SI#B0?
The R1LV3216RSD-7SI#B0 guarantees data retention down to VCC = 2.0 V, as specified in the Low Vcc Data Retention Characteristics table (Page 15) of the datasheet. At this voltage, standby current remains ≤80 µA at +85°C. Retention is maintained as long as one of three conditions holds: CS2 ≤ 0.2V, CS1# ≥ VCC−0.2V with CS2 ≥ VCC−0.2V, or LB# = UB# ≥ VCC−0.2V with CS1# ≤ 0.2V and CS2 ≥ VCC−0.2V.
Is the R1LV3216RSD-7SI#B0 pin-compatible with other members of the R1LV3216R Series?
Yes, the R1LV3216RSD-7SI#B0 shares identical pinout and footprint with other 52-pin µTSOP (II) variants in the R1LV3216R Series, including R1LV3216RSD-5S% and R1LV3216RSD-7S%. All share the same 52-pin arrangement (Page 2), Pin Description (Page 3), and AC/DC characteristics scaling only with access time (55ns vs. 70ns). The "#B0" suffix denotes tape-and-reel packaging; electrical and mechanical compatibility is preserved across speed grades in the same package variant.
