Core Categories and Model Analysis of Infineon Memory Devices
Infineon memory devices, renowned for their high reliability, low power consumption, and strong anti-interference capabilities, find extensive application across automotive electronics, industrial control, medical equipment, IoT, aerospace, and other sectors. Their core classifications primarily encompass two major series: Static Random Access Memory (SRAM) and Ferroelectric Random Access Memory (F-RAM).

I. Ferroelectric Random Access Memory (F-RAM) — Non-volatile, Suited for Mission-Critical Data Storage
Infineon's F-RAM (Ferroelectric Random Access Memory), centred on the EXCELON™ series, combines four key advantages: ultra-low power consumption, high-speed serial interfaces, instant non-volatility, and infinite read/write endurance. Requiring no battery backup, it retains data indefinitely after power loss, making it an ideal choice for mission-critical data logging.
Mingjiada Electronics' primary focus for recycling includes the following mainstream Infineon F-RAM models and specifications:
- 2 Mb density series: Core models include CY15V102QN-50LHXI, CY15V102QN-50SXE, CY15V102QSN-108SXI, etc., suitable for portable medical devices, automotive intelligent cockpits, and similar applications.
- 4 Mb density series: Core models include CY15V104QN-50SXI and CY15V104QSN-108SXI, supporting SPI/QSPI interfaces at 50 MHz and 108 MHz respectively, suitable for industrial control and IoT sensor applications.
- Other mainstream models: Includes FM25CL64B GTR (64Kbit density), CY15V101QN (1 Mb), CY15V108QN (8 Mb), CY15V116QN (16 Mb), etc. Among these, the FM25CL64B GTR supports a 20 MHz SPI interface with a data retention period of 151 years, making it suitable for industrial control data acquisition applications; High-density variants (8 Mb, 16 Mb) prioritise large-capacity storage, catering to high-end automotive electronics, medical equipment, and similar applications.

II. Static Random Access Memory (SRAM)
Infineon SRAM employs latch circuits based on flip-flops to store data, eliminating the need for periodic refreshes. Data remains indefinitely when powered, offering core advantages of high-speed read/write operations, low power consumption, and high reliability. Capacities range from 256 Kb to 144 Mb.
1. Asynchronous SRAM
Asynchronous SRAM operates without external clock synchronisation, offering flexible access. Density ranges from 256 Kb to 64 Mb.
- Low-Power Asynchronous SRAM: Core models represented by the MOBL™ series operate at 45 ns or faster. Mingjiada's refurbished models include MOBL128K8 and MOBL256K8, all supporting industrial-grade temperature ranges (-40°C to 85°C).
- High-speed asynchronous SRAM: Operating speeds below 25 ns. Certain models incorporate PowerSnooze technology, balancing high-speed access with ultra-low-power sleep modes. Core recycled models include IDT71V65803S and IDT71V3575.
2. Synchronous SRAM
Synchronous SRAM operates in sync with an external clock signal, offering higher data throughput with densities ranging from 9 Mb to 144 Mb.
- Single Data Rate SRAM: Transfers one word of data per clock cycle. Core recovery models include CY7C1049DV33 and CY7C1360AV33, supporting 1.8V and 3.3V power supplies.
- Double/Quad Data Rate SRAM:
The DDR series (DDR-II, DDR-II+) employs a common data bus interface, transferring data on both clock edges. The QDR series (QDR-II, QDR-II+) utilises dual independent data bus interfaces, achieving data transfer rates up to 80 Gbps, suitable for high-end networking and data storage applications.
Discontinued models include CY7C1510B and CY7C16200. Radiation-hardened QDR-II+ SRAM (72 Mb, 144 Mb density) withstands cosmic radiation for satellite constellations and radar applications. Common models include CY7C14400V33-RH and CY7C14400V33, operating at 1.5V to 1.8V supply voltage with a maximum frequency of 250 MHz and 36 Gbps single-chip throughput.
