RISC-V core super SIM chip CC2560A adopts 32-bit RISC-V security core, and the CPU main frequency reaches 120MHzIt supports 7816 transmission interface, the communication rate is 10 times higher than that of the existing super SIM, the computing power is doubled compared to the existing super SIM, and the algorithm performance is improved by more than 2 times on average.
The Flash storage resource of CC2560A reaches 2.5MB, which is 10 times the capacity of existing mainstream SIM chips and twice the capacity of existing super SIM chips.CC2560A can be pre-installed with more than 50 applications.
The chip also has multiple interfaces and is easy to expand. In addition to the 7816 interface, it also adds SWP, QSPI, SPI, I2C, and UART interfaces. The expansion of the external Flash through the SPI/QSPI interface can achieve greater expansion capabilities and can be expanded in multiple scenarios in the field of the Internet of Things. Through multiple interfaces, CC2560A can be packaged with baseband chips, storage chips, Bluetooth chips, biometric chips, satellite positioning chips, etc.
In terms of security, CC2560A is designed in accordance with the national secret level 2 and EAL5+ certification standards. It integrates more than 100 security designs such as bus encryption and verification technology, algorithm anti-DPA attack technology, sensitive signal hiding technology, etc., and supports encrypted storage, international and national secret algorithms, and PUF physical anti-cloning capabilities.

The super SIM based on CC2560A not only integrates two national basic applications: digital identity and digital RMB, but also integrates multiple capabilities such as public transportation, electronic student ID cards, access control, and digital car keys.
China Mobile's first 5G Redcap cellular IoT communication chip
In addition, China Mobile CoreSensor released China Mobile's first 5G Redcap cellular IoT communication chip CM9610a chip designed specifically for low-power 5G IoT devices.
According to reports, CM9610 has the following features:
5G All NetworkCM9610 complies with the 3GPP 5G R17 protocol standard, is compatible with 5G NR and 4G LTE networks, supports global mainstream 5G frequency bands including n1, n3, n28, n41, and n79, and inherits 5G key capabilities such as 5G eMBB's uRLLC, network slicing, and 5G LAN.
High integrationThe CM9610 SIP encapsulates LPDDR memory chips, with high integration and minimalist peripheral BOM design.
Low power consumptionCM9610 adopts low-power architecture design, built-in RISC-V coprocessor, and supports multiple low-power modes.
Easy to use and expandCM9610 has USB2.0 interface, Ethernet interface, 8 independent GPIO ports, 2 USIM interfaces, supports external keyboard and LCD screen with maximum resolution of WVGA.
Xiao Qing said that the 5G Redcap chip solution can flexibly adapt to different network environments and frequency band requirements, and the theoretical peak rates of uplink and downlink can reach 170Mbps (DL) and 120Mbps (UL)operating temperature range -40℃~85℃, adapting to the diversity of industrial environments.
CM9610 also supports access to the mobile OneCyber platform and integrates multiple industry standard interfaces such as USB 2.0, PCM, UART, etc. Thanks to the streamlined RF architecture, optimized number of antennas, and reduced transmit and receive bandwidth, it can achieve lower costs and smaller size.Can be applied to remote inspection, video surveillance, vehicle communication and other scenarios.
Taking the low-altitude economy as an example, Coresun Technology is working with partners to create 5G cellular communication end-side solutions for drones and aircraft based on the CM9610 chip for the low-altitude economy field.
RISC-V based MCU chip
CM32M435R is a secure MCU chip with large capacity, low power consumption, PUF and physical protection against side-channel attacks.This chip uses a 40nm low-power process and is based on a 32-bit RISC-V core..
Xiao Qing said that the chip has three main characteristics:
First, high security. The chip adopts a dual-core design, and the security subsystem is independently controlled by the security core, with a higher security level; it supports physical anti-cloning PUF, TEE and anti-side channel attack, and supports a variety of encryption algorithms.
Second, high performance. The chip has a main frequency of up to 120MHz, FLASH reaches 512KB, SRAM reaches 144KB, and supports multiple interface functions such as USB, Ethernet, SDIO, and DCMI.
The third is multi-function. The chip supports a variety of peripherals, such as 2 ADCs, 2 DACs, 4 rail-to-rail operational amplifiers, and 7 high-speed analog comparators, which can meet the needs of various scenarios.
The chip has been demonstrated in batches in multiple scenarios such as smart homes, smart meters, food safety, etc. in the Ministry of Science and Technology's “Smart and Trusted City Cellular Internet of Things Infrastructure Technology Research and Application Demonstration Project”.
