Althico A726: Processor

Cost-effective and reliable and security microcontroller (MCU) from China.

• The world’s first RISCV architecture chip that complies with PCI and UnionPay security
• Unique design that integrates “security + NFC + Bluetooth” at the same time, BT5.1 + EDR dual mode
• Direct FULL mask 40nm chip
• Ultra-low BBL power consumption, as low as 3uA, no need to switch between main and backup batteries
• No need circuit of a switch on/off
• Dual-row QFN package instead of BGA, higher security
• High integration can save SMT costs, and all functions can be completed on a two-layer PCB layout
• Bluetooth does not need a matching circuit, directly use the matching in the chip
• The storage space of the chip can be fully expanded, RAM can be from 64KB to 4MB, FLASH can be from 512KB to 4MB
• GPIO/UART/SPI/PWM/I2C and other digital interfaces can be arbitrarily extended between any GPIO pins

Features

Advanced encryption and decryption technology

Based on PCI-certified True random number generation technology, the chip applied with high advanced technology for encryption/decryption, authentication, and authenticated encryption. This feature makes it outstanding for copyright protection: nobody can copy or decrypt.

IOMUX technology

GPIO/UART/SPI/PWM/I2C and other digital interfaces can be arbitrarily extended between any GPIO pins

On-chip Bluetooth

Wafer built-in Bluetooth. Bluetooth does not need a matching circuit, directly use the matching in the chip. 150kb high speed: Main thread communication, several times faster than normal

Built-in NFC

Wafer on-chip NFC, direct register access. Main thread communication, faster than normal.

ADC

AC/DC switch: No need for extra driver, chip connection directly. Support 3 sets of differential magnetic stripe card information input, additional 4 channels of 10-bit precision ADC

Expandable memory

The storage space of the chip can be fully expanded, RAM can be from 64KB to 4MB, FLASH can be from 512KB to 4MB.
