Product details
Overview
R1LV0816ASA-5SI from Renesas Electronics is an 8Mb low-power static RAM organized as 524,288 words × 16 bits or 1M words × 8 bits, operating from a single 2.4–3.6V supply with 55 ns access time and −40°C to +85°C industrial temperature range. It delivers 1.2 μA standby current at 3.0V and supports byte/word mode selection via BYTE# pin for flexible memory expansion in battery-backed systems.
For engineers reviewing the R1LV0816ASA-5SI datasheet, R1LV0816ASA-5SI pinout, R1LV0816ASA-5SI application, or R1LV0816ASA-5SI equivalent, key selection criteria include its TSOP-I 48-pin package, TTL-compatible I/O, no-refresh operation, OR-tie capable three-state outputs, and dual-mode addressing (A−1/A0–A18) for embedded control, portable instrumentation, and industrial data logging.
Technical Context
The R1LV0816ASA-5SI implements a fully static CMOS memory array fabricated on 0.15 µm process, with independent column/row decoders and sense/write amplifiers enabling true random-access read/write without clocks or refresh cycles. Its dual-bank chip select architecture (CS1#, CS2) and separate upper/lower byte enables (UB#, LB#) support seamless memory mapping in 8-bit and 16-bit bus systems.
BYTE# pin configures address interpretation: when high, A−1 is ignored and standard word addressing (A0–A18) applies; when low, A−1 becomes active for byte-mode addressing, allowing 1M × 8-bit organization. Standby current drops to 1.2 µA by asserting CS2 = low or CS1# = high, with data retention supported down to 1.5V VCC.
Key Specifications

FAQ
What is the maximum access time specification for the R1LV0816ASA-5SI under industrial temperature conditions?
The R1LV0816ASA-5SI has a guaranteed maximum access time of 55 ns across the full operating temperature range of −40°C to +85°C, measured at VCC = 2.4–3.6V. This value is validated per AC Characteristics Table on page 8 of the official Renesas datasheet REJ03C0395-0100 Rev.1.00, ensuring deterministic timing for 18 MHz bus interfaces in industrial environments.
How does the BYTE# pin affect address decoding in the R1LV0816ASA-5SI?
When BYTE# = high, the R1LV0816ASA-5SI operates in word mode using A0–A18 for 524,288-word addressing; A−1 is ignored. When BYTE# = low, it switches to byte mode, activating A−1 and using A−1–A17 for 1,048,576-word addressing. This dual-mode capability allows one R1LV0816ASA-5SI design to serve both 8-bit and 16-bit microcontroller platforms without hardware changes.
What is the minimum VCC required to retain data in the R1LV0816ASA-5SI during standby?
The R1LV0816ASA-5SI maintains data integrity down to VCC = 1.5V in data retention mode, as specified in the Data Retention Characteristics table (page 15). This low threshold enables robust operation during brown-out conditions and extends usable battery life in backup configurations-critical for applications like portable medical monitors and industrial loggers.
Can the R1LV0816ASA-5SI be used in a 3.3V system with TTL-level peripherals?
Yes, the R1LV0816ASA-5SI supports 3.3V operation (VCC = 2.4–3.6V) and features TTL-compatible inputs and outputs. Its VOH ≥ 2.4V (IOH = −1mA) and VOL ≤ 0.4V (IOL = 2mA) meet standard TTL voltage thresholds, allowing direct connection to 3.3V microcontrollers, FPGAs, and logic families without level-shifting circuitry.
What package type and dimensions does the R1LV0816ASA-5SI use?
The R1LV0816ASA-5SI uses a 48-pin plastic thin small outline package (TSOP-I) with 12 mm × 20 mm body dimensions and 0.50 mm pin pitch. This JEDEC-standard package supports automated assembly, offers excellent thermal performance for its class, and is mechanically compatible with widely available socket footprints and reflow profiles.
