Product details
Overview
R1RP0416DSB-0PR#D1 from Renesas Electronics is a 4-Mbit high-speed static RAM organized as 256-kword × 16-bit, fabricated using CMOS 6-transistor memory cell technology. It delivers 10 ns max access time, operates on single 5.0 V ±10% supply, and supports byte-selectable read/write operations for cache and buffer applications in industrial control systems.
For engineers reviewing the R1RP0416DSB-0PR#D1 datasheet, R1RP0416DSB-0PR#D1 pinout, R1RP0416DSB-0PR#D1 application, or R1RP0416DSB-0PR#D1 equivalent, key selection criteria include wide-temperature operation (−40°C to +85°C), TTL-compatible I/O, center VCC/VSS pinout, and 44-pin TSOPII package compatibility with high-density memory subsystems.
Technical Context
The R1RP0416DSB-0PR#D1 implements a fully static architecture requiring no clocks or timing strobes, enabling deterministic access and cycle times. Its dual-byte select (UB#/LB#) enables independent 8-bit data path control, while direct TTL compatibility ensures seamless interfacing with legacy microcontrollers and FPGAs without level-shifting.
It features separate standby current modes: 40 mA TTL standby and 5 mA CMOS standby, selectable via input voltage thresholds. The device uses center VCC/VSS pin arrangement to minimize power distribution inductance and supports simultaneous address/data bus sharing through high-impedance tri-state outputs during deselect or disable states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address input | 18-bit address bus supporting full 256-kword decoding; no internal multiplexing |
| I/O1–I/O16 | Data input/output | Bidirectional 16-bit data bus; high-impedance when CS#, OE#, LB#, or UB# inactive |
| CS# | Chip select | Active-low enable controlling all internal operations; must be stable before address setup |
| OE# | Output enable | Active-low control for output drivers only; does not affect write or standby state |
| WE# | Write enable | Active-low signal initiating write cycles; sampled with CS# and byte selects to define write boundaries |
| UB# / LB# | Upper/lower byte select | Independent 8-bit write/read masking; allows partial-word updates without read-modify-write |
| VCC / VSS | Power / ground | Center-placed VCC and VSS pins reduce IR drop and improve noise immunity across wide data bus |
| NC | No connection | Unbonded pin; must remain unconnected per Renesas design rules |
Key Features
| Feature | Design Value |
|---|---|
| Fully static operation | No clocks, refresh, or timing strobes required - simplifies timing-critical system design and eliminates hidden latency |
| Byte-selectable I/O | Independent UB# and LB# controls enable 8-bit granularity writes/reads - avoids bus contention and reduces controller overhead |
| TTL-compatible I/O | All inputs accept VIH ≥ 2.2 V and VIL ≤ 0.8 V; outputs drive VOH ≥ 2.4 V and VOL ≤ 0.4 V - interoperable with 5 V logic families |
| Low-power standby modes | CMOS standby draws only 5 mA at f = 0 MHz - suitable for intermittent-data buffering in energy-constrained industrial nodes |
| Wide-temperature reliability | Specified over −40°C to +85°C with validated AC/DC parameters - supports deployment in automotive under-hood and factory automation environments |

FAQ
What is the operating voltage range for R1RP0416DSB-0PR#D1?
The R1RP0416DSB-0PR#D1 operates on a single 5.0 V supply with a tolerance of ±10%, meaning its valid DC operating range is 4.5 V to 5.5 V. This specification is verified across the full −40°C to +85°C temperature range and aligns with standard TTL logic voltage levels. The R1RP0416DSB-0PR#D1 does not support 3.3 V operation, and applying voltages outside this range may cause permanent damage or undefined behavior.
Does R1RP0416DSB-0PR#D1 support partial-word writes?
Yes, the R1RP0416DSB-0PR#D1 supports partial-word writes via dedicated UB# (upper byte select) and LB# (lower byte select) control inputs. When only one of these signals is asserted low during a write cycle with WE# and CS# active, only the corresponding 8-bit portion of I/O1–I/O16 is updated. This eliminates the need for read-modify-write sequences and reduces bus traffic in applications like register-mapped peripherals. The R1RP0416DSB-0PR#D1 datasheet confirms this behavior in the Operation Table and AC timing waveforms.
What is the maximum operating current for R1RP0416DSB-0PR#D1 during active read cycles?
The R1RP0416DSB-0PR#D1 draws a maximum operating current of 170 mA during active read cycles at 10 ns speed grade, measured under worst-case conditions (Ta = −40°C to +85°C, VCC = 5.0 V ±10%, all outputs loaded). This value is specified in the DC Characteristics table on page 5 of the R10DS0285EJ0100 datasheet. The R1RP0416DSB-0PR#D1 also specifies lower current for 12 ns variants (160 mA), confirming speed-grade dependency.
Is R1RP0416DSB-0PR#D1 pin-compatible with other devices in the R1RP0416DI Series?
Yes, all members of the R1RP0416DI Series-including R1RP0416DGE-2PI, R1RP0416DSB-0PI, and R1RP0416DSB-2PI-share identical pinouts and electrical interfaces. The R1RP0416DSB-0PR#D1 uses the same 44-pin TSOPII package and center VCC/VSS configuration as documented in the Pin Arrangement diagram. Differences are limited to access time (10 ns vs. 12 ns) and package variant (TSOPII vs. SOJ), not pin function or assignment. The R1RP0416DSB-0PR#D1 maintains full functional and mechanical compatibility within its package family.
What is the meaning of "center VCC and VSS type pin out" for R1RP0416DSB-0PR#D1?
"Center VCC and VSS type pin out" means that VCC and VSS pins are positioned near the center of the 44-pin TSOPII package-specifically pins 22 and 23-rather than at opposite ends. This layout minimizes power distribution impedance across the wide 16-bit data bus, reduces simultaneous switching noise, and improves signal integrity in high-speed parallel memory interfaces. The R1RP0416DSB-0PR#D1 datasheet confirms this arrangement in the Pin Arrangement diagram and highlights its benefit for stable operation in electrically noisy industrial environments.
