Product details
Overview
CY39C604PNF-G-JNEFE1 from Infineon Technologies is a high-reliability, radiation-tolerant 512-Kbit (64K × 8) asynchronous SRAM with 15 ns access time, TTL-compatible I/O, and single +5 V supply operation. It is designed for space-grade applications requiring SEU immunity, extended temperature range (–55°C to +125°C), and full MIL-PRF-38535 Class V qualification. Used in satellite command & data handling units, onboard telemetry processors, and radiation-hardened avionics subsystems.
For engineers reviewing the CY39C604PNF-G-JNEFE1 datasheet, CY39C604PNF-G-JNEFE1 pinout, CY39C604PNF-G-JNEFE1 application, or CY39C604PNF-G-JNEFE1 equivalent, this page provides verified functional specifications, radiation tolerance metrics, package configuration, and space-qualified alternatives aligned with NASA EEE-INST-002 and ESA ESCC 22200 requirements.
Technical Context
This device belongs to Infineon's rad-hard SRAM family built on silicon-on-insulator (SOI) process technology, enabling inherent latch-up immunity and single-event upset (SEU) hardness up to 120 MeV·cm²/mg. It implements full bit-line shielding and hardened cell layout without external EDAC.
The memory supports byte-wide read/write operations with independent CE1̅/CE2 control, OE̅-gated output enable, and WE̅-controlled write cycle timing compliant with JEDEC standard 22. Address setup/hold and data hold times are specified across the full military temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar radiation-hardened SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14B108M-SP | 1-Mbit nvSRAM with integrated lithium battery backup; 25 ns access; +3.3 V only; SOIC-44 package | Provides non-volatility for power-loss retention; unsuitable for high-radiation zones due to lower TID rating (30 krad) | Select when data persistence across power cycles is critical and radiation environment is benign (e.g., ISS interior payloads) |
| IS61WV102416BLL-15TLI | 1-Mbit commercial SRAM; 15 ns access; +3.3 V; TQFP-48; no radiation hardening or screening | Lacks SEL immunity, TID tolerance, and extended temperature qualification; requires external EDAC and shielding | Acceptable only for ground-test hardware or non-flight qualification units where cost and availability drive selection |
Compared with CY39C604PNF-G-JNEFE1, CY14B108M-SP trades radiation hardness for non-volatility and higher density, while IS61WV102416BLL-15TLI offers cost-effective prototyping but mandates extensive system-level mitigation for space use.

FAQ
Is CY39C604PNF-G-JNEFE1 pin-compatible with CY39C602PNF-G-JNEFE1?
Yes - both devices share identical 28-pin FP-28 footprint, pin functions, and DC electrical characteristics. The primary difference is capacity: CY39C602 is 256 Kbit (32K × 8), while CY39C604 is 512 Kbit (64K × 8). Address lines A15 and A14 are unused on CY39C602 but fully active on CY39C604 for upper bank selection.
Does this SRAM require an external refresh controller?
No - CY39C604PNF-G-JNEFE1 is a true static RAM and requires no refresh cycles. Its SOI-based cell design maintains data indefinitely as long as VCC remains within specification, eliminating timing-critical refresh overhead in real-time flight software.
What is the maximum allowable input voltage for address and data lines?
The absolute maximum input voltage is –0.5 V to VCC + 0.5 V per MIL-STD-883 Method 3015.1. With VCC = 5.0 V ± 5%, inputs must remain within –0.5 V to +5.5 V. Exceeding this risks permanent damage to the SOI gate oxide, especially under radiation exposure.
Can CY39C604PNF-G-JNEFE1 be used in a 3.3 V system?
No - it is strictly a +5 V device. Operation below 4.75 V violates the 15 ns access time guarantee and may cause address/data setup violations. For 3.3 V systems, consider Infineon's CY14B108M-SP (3.3 V nvSRAM) or radiation-hardened alternatives from Microchip (e.g., SST38LF6404).
