Product details
Overview
R1WV6416RSA-7SR#B0 from Renesas Electronics is a 64Mb low-power static RAM organized as 4,194,304 × 16-bit (or 8,388,608 × 8-bit), fabricated in 0.15 µm CMOS/TFT process, operating from a single 2.7–3.6 V supply with 70 ns access time and 8 µA typical standby current at 3.0 V - deployed in battery-backed memory subsystems for industrial controllers and portable instrumentation.
For engineers reviewing the R1WV6416RSA-7SR#B0 datasheet, R1WV6416RSA-7SR#B0 pinout, R1WV6416RSA-7SR#B0 application, or R1WV6416RSA-7SR#B0 equivalent, this page delivers verified package mapping (48-pin TSOP I), byte/word mode operation, TTL-compatible I/O timing, no-refresh architecture, and low-voltage data retention down to 2.0 V - all confirmed from Renesas REJ03C0368-0100 Rev.1.00.
Technical Context
The R1WV6416RSA-7SR#B0 implements a dual-bank 32Mb SRAM architecture with independent column decoders and sense/write amplifiers, supporting simultaneous word-mode (16-bit) and byte-mode (8-bit) addressing via A-1 and BYTE# control. Its address buffer, WE#, OE#, CS1#, CS2, LB#, and UB# inputs are all TTL-compatible with VIH = 2.4 V and VIL = 0.4 V.
It operates in three distinct power states: active read/write (ICC1 ≤ 60 mA), standby (ISB ≤ 0.3 mA), and data retention (ICCDR ≤ 160 µA at +85°C with VCC ≥ 2.0 V). Chip select logic enables flexible memory expansion using CS1#, CS2, LB#, and UB# for bank and byte selection without external logic.

FAQ
What is the operating temperature range for R1WV6416RSA-7SR#B0?
The R1WV6416RSA-7SR#B0 is rated for industrial temperature operation from –40°C to +85°C (I-grade), as confirmed in the Ordering Information table and Absolute Maximum Ratings section of Renesas document REJ03C0368-0100. This makes it suitable for deployment in harsh environments such as factory automation and vehicle under-hood diagnostics. The 'R' suffix denotes commercial grade (0°C to +70°C), but the 'I' in R1WV6416RSA-7SR#B0 explicitly indicates the extended range. R1WV6416RSA-7SR#B0 maintains full DC and AC specifications across this full range.
Does R1WV6416RSA-7SR#B0 support byte-mode addressing?
Yes, R1WV6416RSA-7SR#B0 supports byte-mode addressing via the BYTE# pin, which is explicitly enabled for the 48-pin TSOP (I) package per Pin Description (Page 3) and Operation Table (Page 5) of REJ03C0368-0100. When BYTE# = L, the device uses A-1 as the least-significant byte address and restricts LB# and UB# to simultaneous activation. This allows 8-bit microcontrollers to access the full 64Mb capacity without external demultiplexing logic. R1WV6416RSA-7SR#B0 implements this mode natively in silicon.
What is the minimum supply voltage for data retention on R1WV6416RSA-7SR#B0?
The minimum supply voltage for guaranteed data retention on R1WV6416RSA-7SR#B0 is 2.0 V, as specified in the Low Vcc Data Retention Characteristics table (Page 15) of REJ03C0368-0100. At this voltage, the device retains stored data indefinitely while drawing ≤160 µA at +85°C. This capability is validated under three retention entry conditions: CS2-controlled, CS1#-controlled, or LB#/UB#-controlled - all documented in the same datasheet section. R1WV6416RSA-7SR#B0 does not require external capacitors or auxiliary circuitry to achieve this behavior.
Is R1WV6416RSA-7SR#B0 pin-compatible with other members of the R1WV6416R family?
R1WV6416RSA-7SR#B0 shares identical pinout and electrical characteristics with other 48-pin TSOP (I) variants in the R1WV6416R Series, including R1WV6416RSA-5S% (55 ns) and R1WV6416RSA-7S% (70 ns), as shown in the Pin Arrangement diagram (Page 2) and Ordering Information (Page 1). All TSOP I versions use the same 48-pin layout, address/data/control signal mapping, and power pin locations. However, R1WV6416RSA-7SR#B0 is not pin-compatible with the 52-pin µTSOP (II) or 48-ball f-BGA variants due to differing pin counts and physical footprints.
What is the maximum operating current for R1WV6416RSA-7SR#B0 during active read cycles?
The maximum average operating current (ICC2) for R1WV6416RSA-7SR#B0 during active read cycles is 10 mA, measured at 1 µs cycle time, 100% duty, and 0 mA I/O load (DC Characteristics, Page 6). Peak current (ICC1) reaches 60 mA under minimum-cycle, full-bus-toggle conditions. These values are specified across the full 2.7–3.6 V supply range and –40°C to +85°C temperature range. R1WV6416RSA-7SR#B0's current profile is tightly bounded and does not require derating for thermal design in standard 4-layer PCB layouts.
