Zhaoxun Hengda announced the launch of its latest research and development results - MH1905. The product is built on a heterogeneous asymmetric architecture and integrates a high-performance application processor (AP) and a security processor (SP), bringing disruptive solutions to consumer electronics, industrial control, the Internet of Things and other fields.
Specifically, the AP system of MH1905 uses the ARM Cortex-A5 core, with a maximum operating frequency of up to 1.2GHz, which can easily handle complex operating system tasks. At the same time, it supports 720p resolution video output and up to 5 million pixel camera access, providing strong support for applications such as image processing and video surveillance. In addition, the AP is also compatible with multiple memory types and integrates a Gigabit Ethernet MAC to meet the needs of high-speed data transmission.

In terms of security, the SP processor of MH1905 also performs well. It uses a 32-bit RISC core with a maximum operating frequency of 200MHz, focusing on the processing of real-time and security applications. SP has a built-in powerful encryption engine, supports multiple encryption algorithms such as AES, DES, TDES, RSA, ECC, SHA, and provides hardware encryption acceleration. In addition, SP also has anti-tampering pins, sensitive data such as key storage areas powered by button batteries, and data retention time of more than five years; it also has anti-tampering functions, providing all-round protection for data security. [See Figure 2]
It is worth mentioning that the two subsystems of the MH1905 processor exchange data through an efficient cross switch, ensuring the collaborative work between the AP and the SP. At the same time, the processor also shares a variety of peripheral interfaces, such as USB, I2C, SPI, etc., and provides practical functions such as general input and output interface (GPIO) and barcode engine, further enhancing its application flexibility. In addition, MH1905 adopts advanced FCCSP packaging technology, with a size of 13 x 13mm, 361 solder balls, and a pitch of 0.65mm, which is very suitable for embedded applications.
MH1905's unique dual-subsystem architecture not only improves the performance and security of the processor, but also provides a more comprehensive and efficient solution for various application scenarios. In order to facilitate customers and enthusiasts to quickly get started with development, Zhaoxun Hengda has launched the SecurePi series modules based on MH1905 with its partners, including SP2301, SP2302, etc., which are suitable for application scenarios of various electronic devices.
