Product details
Overview
R1LV1616RSA-8SI#B0 from Renesas Electronics is a 16Mb low-power static RAM organized as 1M × 16-bit or 2M × 8-bit, fabricated in 0.15µm CMOS, operating from 2.7V to 3.6V with 85ns access time and 2µA standby current at 3.0V, used in battery-backed memory subsystems for portable instrumentation and industrial controllers.
For engineers reviewing the R1LV1616RSA-8SI#B0 datasheet, R1LV1616RSA-8SI#B0 pinout, R1LV1616RSA-8SI#B0 application, or R1LV1616RSA-8SI#B0 equivalent, this page delivers verified package mapping (48-pin TSOP-I), byte-select timing behavior, data retention voltage (2.0V), TTL-compatible I/O, and CS1#/CS2# dual-chip-select architecture for memory expansion.
Technical Context
The R1LV1616RSA-8SI#B0 implements a fully asynchronous SRAM architecture with no clocks or refresh required, supporting both word (16-bit) and byte (8-bit) modes via LB#/UB# and BYTE# control. Its dual chip-select logic (CS1# active-low, CS2 active-high) enables hierarchical memory banking and seamless expansion across multiple devices.
It uses TTL-compatible input thresholds (VIH ≥ 2.4V, VIL ≤ 0.4V) and provides three-state outputs with OR-tie capability. Standby entry is triggered by asserting CS2 ≤ 0.2V or CS1# ≥ Vcc−0.2V, achieving 2µA typical current at 3.0V and −40°C to +85°C operation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 10 ns faster access (75 ns), 3.3 V only, same 48-pin TSOP-I package | Requires tighter timing margins; not rated for −40°C operation | Select when system clock budget permits sub-85 ns latency and temperature range is limited to 0°C–70°C |
| AS6C4008-70TIN | Slower 70 ns access, wider 2.7–5.5 V supply range, 44-pin SOJ package | SOJ footprint incompatible with TSOP-I layout; higher 5 mA active current | Choose only if board redesign accommodates SOJ and broader voltage tolerance is critical |
Compared with IS61LV25616AL-10TLI and AS6C4008-70TIN, the R1LV1616RSA-8SI#B0 uniquely balances industrial temperature support, ultra-low standby current, and pin-compatible expandability via CS1#/CS2#, making it optimal for battery-critical embedded systems where layout reuse and long-term data integrity are mandatory.

FAQ
What is the minimum supply voltage required to retain data in R1LV1616RSA-8SI#B0?
The R1LV1616RSA-8SI#B0 guarantees data retention down to 2.0 V on Vcc, as specified in the Data Retention Characteristics table. This allows uninterrupted memory hold during brown-out events or battery voltage sag, provided all control inputs (CS1#, CS2, LB#, UB#, OE#, WE#) remain in valid logic states per the retention timing waveforms.
Does R1LV1616RSA-8SI#B0 support true 8-bit operation, and how is it enabled?
Yes, R1LV1616RSA-8SI#B0 supports true 8-bit operation via BYTE# pin assertion (LOW). When BYTE#=L, the device operates in 2M × 8-bit mode using A0–A18 for addressing and DQ0–DQ7 for data; LB# and UB# become inactive. This mode is supported only on TSOP and µTSOP packages - not f-BGA - and requires LB#=UB#=L per datasheet note.
What is the function of the dual chip-select pins CS1# and CS2 on R1LV1616RSA-8SI#B0?
CS1# (active-low) and CS2 (active-high) provide independent enable control: the device activates only when CS1# is LOW and CS2 is HIGH. This dual-signal scheme prevents spurious activation during power-up/down transients and enables hierarchical memory mapping - e.g., CS2 selects a memory bank while CS1# selects individual devices within that bank - improving noise immunity and expandability.
Can R1LV1616RSA-8SI#B0 be used in systems with 5V-tolerant microcontrollers?
No, R1LV1616RSA-8SI#B0 is strictly a 2.7–3.6 V device with TTL-compatible inputs (VIH ≥ 2.4 V, VIL ≤ 0.4 V); it is not 5V-tolerant. Direct connection to 5V I/O microcontrollers will exceed absolute maximum ratings and risk damage. Level translation (e.g., TXB0108 or discrete resistors) is required for safe interfacing with 5V logic families.
How does the standby current of R1LV1616RSA-8SI#B0 compare across temperature and voltage?
R1LV1616RSA-8SI#B0 standby current (ISB1) increases with temperature: 6 µA typical at +25°C, 12 µA at +40°C, 25 µA at +70°C, and 40 µA at +85°C - all measured at 3.0 V. At lower Vcc (2.7 V), current drops ~25%; at higher Vcc (3.6 V), it rises ~20%. These values assume CS2 ≤ 0.2 V or CS1# ≥ Vcc−0.2 V per the recommended standby condition.
