March 23 news, recently, Shanghai Fudan Microelectronics Group Co., Ltd. launched a low-power MCU series with integrated capacitive touch button controller - FM33FR0. This series has been optimized and upgraded on the basis of the FM33LC0 series, and is designed and developed for the application needs of home appliances.
At the same time, the FM33FR0 series adds more peripherals, integrates a capacitive touch button controller, dual CAN and dual LIN, and maintains a consistent excellent low power performance, combining function and performance, which is a powerful choice for white goods, smart home and other fields.
The FM33FR0 series is based on a 32-bit ARM Cortex-M0 core with a maximum clock frequency of 48MHz, providing a maximum of 384KB Program FLASH, 8KB Data FLASH (500,000 erasures), flash support for ECC; maximum 32KB RAM with parity; support for LQFP44 / LQFP48 / LQFP64 / LQFP80 / LQFP100 multiple packages.
In addition, the FM33FR0 features the following highlights:
Integrated capacitive touch button controller with Touch function:
- Supports up to 14 independent key channels, self-capacitance detection, and mutual capacitance detection
-Support key capacitance range: 5~50pF
-Baseline tuning
-Low power consumption
-Waterproof function
- Hardware filtering
Integrated LCD segment display driver circuit, maximum support 4COM×44SEG / 6COM× 42SEG / 8COM× 40SEG.
Integrated LED segment code driver, maximum support 8SEG×32DIG.
Built-in keyboard scanning function, up to 4×4 to achieve 16 keys to scan.
Supports up to 2 independent FSCAN modules for classic CAN bus data transceiver and dual CAN buses with CAN 2.0A and 2.0B protocols.
Supports up to 6 independent UARTs, 2 of which support hardware LIN communication.
Supports up to two independent I2C-SMBus, enabling synchronous communication between the MCU and external I2C or SMBus devices. There are also up to 4 I2C hosts.
Features a 12bit 2Msps SAR-ADC with a maximum of 23CHs for sampling of temperature, battery voltage, or external input DC/AC signals.
Two comparators are integrated, one of which is a rail-to-rail comparator that supports rail-to-rail inputs and multiple power modes, and one is a low-power comparator with a typical power consumption of 200nA.
Built-in HDIV hardware divider helps the software speed up division operations.
The built-in PGL function enables simple glue logic, helping to reduce the number of logic devices on the PCB of the system design.
Features a TAU timer array unit that supports 2 groups of 12 independent 16-bit up counters.
Built-in security features. It has AES hardware computing unit 128/192/256-bit, supports ECB/CBC/CTR/GCM/GMAC mode; built-in TRG; built-in world-unique identification code UID number.
Supports the household appliance safety standard IEC 60730 and the industry-related standard IEC 61508.
In order to help the majority of clients achieve rapid development, for the FM33FR0 series Touch peripherals, the Fudan micro MCU team has simultaneously developed a graphical parameter interface. Customers can intuitively configure parameters such as scan configuration, threshold, sensitivity, etc. through the waveform, and directly generate code for project application.
In addition, in order to help clients achieve a faster and more effective product development process, for a long time, the Fudan micro MCU team has always been committed to the renewal and improvement of the ecosystem. Each MCU series product of Fudan Micro is equipped with a corresponding development board to assist engineers in functional verification; professional vertical online chip configuration tool Rubik's Cube MFANG, which can help chip configuration and generate engineering code with one click, and now supports FM33LC0 series and FM33LG0 series, FR0 series is under synchronous development; Fudan Micro Developer Forum provides a wealth of software and hardware development materials for the majority of Complex Micro MCU users for user reference and exchange.
The FM33FR0 series is a highly integrated, easy-to-use, high-capacity, low-power MCU product that combines functionality and performance to meet a variety of client application scenarios. The Fudan micro MCU team adheres to the company's purpose of achieving the future with a special "core", and will continue to investigate the needs of the client and further iterative upgrade of the product.
