Product details
Overview
8403616JA from Renesas Electronics is a 16K-bit (2K × 8) CMOS static RAM with TTL-compatible I/O, 25ns max access time (commercial grade), 5V supply, and 24-pin SOIC packaging. It operates in standby mode when CS is high, reducing system power consumption. Used in embedded controllers, industrial PLCs, and legacy instrumentation requiring non-refreshed memory with battery backup capability (LA variant).
For engineers reviewing the 8403616JA datasheet, 8403616JA pinout, 8403616JA application, or 8403616JA equivalent, this page delivers verified timing specs, military-grade reliability data, package-confirmed pin mapping, and direct alternatives for SRAM replacement in space-constrained, temperature-varying, or low-power-retention designs.
Technical Context
The 8403616JA implements fully static asynchronous operation-no clocks or refresh cycles required. Its address decoding and I/O control logic are built on high-reliability CMOS, eliminating alpha-particle soft errors and enabling stable operation across –40°C to +85°C (industrial grade).
It supports three distinct operating modes: active read (CS=L, OE=L, WE=H), active write (CS=L, WE=L), and TTL-level standby (CS=H), with automatic transition to low-current CMOS standby (ISB1 ≤ 0.1mA) when inputs meet VHC/VLC thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8), enabling byte-wide data bus interfacing without external demultiplexing |
| Access Time | 25 ns max (commercial grade), defining minimum cycle time for reliable read/write under 5V ±10% supply |
| Supply Voltage | 4.5 V to 5.5 V, compatible with standard TTL/CMOS 5V logic rails and legacy power domains |
| Standby Current | 0.1 mA max (ISB1, LA version), allowing >1-year retention on a 2V coin cell in battery-backup systems |
| Operating Temp | –40°C to +85°C (industrial grade), validated for use in factory automation and outdoor telemetry hardware |
| I/O Compatibility | TTL input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and output drive (VOH ≥ 2.4 V @ –4 mA, VOL ≤ 0.4 V @ 8 mA) |
| Package | 24-pin SOIC (PSG24), 300-mil width, surface-mount compatible with standard reflow profiles |
Pinout & Package
8403616JA is supplied in a 24-pin gull-wing SOIC (PSG24) package, 300-mil body width, JEDEC MS-013 compliant, with 0.050" lead pitch and matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus accepting 0–2047 row selection; latched on CS or WE edge per timing mode |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit TTL-compatible data path; high-impedance when CS=H or during write setup/hold |
| CS | Chip Select | Active-low enable controlling device activation and automatic entry into standby (ISB) or full standby (ISB1) modes |
| WE | Write Enable | Active-low signal qualifying write cycles; must overlap CS=L to initiate data latch into memory array |
| OE | Output Enable | Active-low control for output drivers; allows read data gating independent of CS state |
| VCC | Power Supply | Primary 5V supply pin; decoupling required within 10 mm of pin per high-speed switching current demands |
| GND | Ground Reference | Signal and power return; requires low-inductance connection to minimize noise coupling into I/O and address lines |
Key Features
| Feature | Design Value |
|---|---|
| Static Operation | No clock or refresh circuitry needed-simplifies system design and eliminates dynamic power overhead and timing-critical refresh scheduling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 32M-bit (2M × 16), 45ns access, 3.3V core, SOIC-44; higher density but incompatible voltage and bus width | Requires level shifters and address/data bus redesign; unsuitable for drop-in 5V/8-bit systems | Select only when upgrading system architecture to 3.3V and wider data paths; not a functional substitute for 8403616JA |
| AS6C1008-25ZIN | 1M-bit (128K × 8), 25ns access, 5V, SOIC-28; same voltage and bus width but larger footprint and higher standby current (2µA vs 0.1µA) | Compatible pinout except for extra address pins (A14–A16); requires PCB layout change and firmware address remapping | Use for cost-sensitive upgrades where board space allows and battery backup is not required |

FAQ
What is the maximum operating temperature range supported by the 8403616JA?
The 8403616JA is qualified for industrial temperature operation from –40°C to +85°C. This rating is confirmed in the "Recommended Operating Temperature and Supply Voltage" table and applies specifically to orderable variants with suffix 'I' (e.g., 6116SA25TPGI). Commercial-grade versions are limited to 0°C to +70°C.
Does the 8403616JA require external refresh circuitry?
No, the 8403616JA is a fully static RAM and requires no clocks or refresh cycles. Its internal CMOS latches retain data indefinitely as long as VCC remains within specification and CS is held high during standby. This eliminates refresh overhead and simplifies system timing design.
Is the 8403616JA pin-compatible with the original IDT6116SA/LA series?
Yes-the 8403616JA is a Renesas rebranded continuation of the IDT6116SA/LA family. Pinout, timing, and electrical specifications are identical across equivalent speed/package/grade variants, including 24-pin SOIC (PSG24), DIP (PTG24), and ceramic DIP (SD24/CD24) configurations.
What is the data retention capability of the 8403616JA under battery backup?
Data retention at 2V is supported only in LA-version devices (e.g., 6116LA25SOGI). The 8403616JA datasheet confirms VDR = 2.0V min and ICCDR ≤ 1.5 µA (typ.) over full industrial temperature range, enabling multi-year retention on small lithium coin cells without additional regulation.
Can the 8403616JA be used in military-aerospace applications?
Yes-when ordered in ceramic DIP packages (SD24 or CD24) with military temperature grade (–55°C to +125°C) and screened to MIL-STD-883 Class B, the 8403616JA meets requirements for high-reliability aerospace and defense systems. These variants are explicitly listed in the "Ordering Information - Military" section.
