GigaDevice has launched brand-new GD32F170/190 series 32-bit 5V wide-voltage cost-optimized MCUs based on the 72MHz Cortex-M3 core. It continues to provide solutions of an excellent price-performance ratio for industrial and home appliance applications with high anti-noise performance, high reliability, high level of integration, and high efficiency.
January 20, 2016 – GigaDevice, an industry-leading semiconductor supplier, recently announced the launch of its 5V anti-noise and cost-optimized GD32F170 and GD32F190 MCUs based on the ARM Cortex-M3 core. With 5V wide-voltage adaptability, the new MCUs aim to pave way for the application requirements in rigorous environments such as the industrial site, white goods, and human-machine interface. They not only integrate excellent processing performance and the real-time feature but also adopt peripheral resources such as newly designed high-performance ADC, multi-channel comparator, OPA, and segment liquid crystal driver. In this way, they provide better support for imbedded applications such as high-speed signal collection, mixed signal processing, motor control, and LCD; with excellent EMC and ESD capabilities, they comply with industrial-grade high reliability and temperature standards. As the newest members of the GD32 MUC family, the GD32F170 and GD32F190 series uphold the core value of better performance and more optimized costs of the GD32 cost-optimized MCUs; they contain up to 16 models for options and remain perfectly compatible with existing products in terms of software and pins, thus making it easier to achieve code transplant, extension, and upgrade.
With a brand-new process design, the GD32F170/190 series products can work in the 2.5V-5.5V wide-voltage application environment; they can also conveniently connect to the 5V system without any extra voltage converter, while the I/O interface can stand the 5V electrical level. They support advanced power management and have three power-saving modes. In the case of external power supply from batteries, the standby current in the built-in high-precision and calibrated RTC is lower than 1uA. These products each have a core whose highest clock frequency is 72MHz, and they are equipped with built-in 16KB-64KB flash and 4KB-8KB SRAM; causing no wait in core access to the flash at high speed, their working performance can reach 210DMIPS at the highest dominant frequency and their code execution efficiency at the same dominant frequency is better than its peers on the market by 20% and superior to the Cortex-M0+ products by more than 35%.
The 5V wide-voltage cost-optimized MCU integrates a diversity of innovative peripheral resources on chip. Its 16-bit advanced timer supporting three-phase PWM mutually supplementary output and the Hall sensor interface can be used for vectoring control. In addition, it has as many as ten 16-bit general-purpose timers, one 32-bit general-purpose timers, two 16-bit basic timers, and one multichannel DMA controllers. Its peripheral interface resources include up to two USARTs, three SPIs, three fast I2Cs, and two I2Ss.Of these resources, the SPI interface can work at the highest frequency of 30MHz and supports 4-line synchronous serial mode for convenient connection to the external large-capacity NOR flash to make fast access. The fast I2C interface is the first of its kind compatible with the technical specification for the resident ID certificate authentication interface, completely suitable for localized custom industrial applications. Besides, it comes with a CEC bus hardware circuit support HDMI for the sake of home multimedia devices and integrates the TSI especially for touch control applications such as key press and slide. Its built-in LCD controller supports connection to the STN graphic display unit and can directly drive 256 (8×32) segment codes to achieve high-quality and high-contrast liquid crystal display. Up to 80% of available GPIOs have optional features and support port remapping, while they meet various application requirements for excellent flexibility and ease of use.
The GD32F170/190 series MCUs also provide a higher level of integration for mixed signal control in motor, energy efficiency, sampling, and so on. Their enhanced analog peripherals include the 12-bit high-speed ADC whose sampling rate is up to 2MSPS and support up to 16 multiplex channels as well as the 16-bit hardware filtered oversampling feature and the resolution configurability feature. In addition, the MCUs each have two 12-bit DACs, two rail-to-rail I/O analog voltage comparators, three OPAs, and programmable reference current/voltage output. Besides, they each have two CAN2.0B bus controllers available on chip and are the first MCUs coming with a built-in CAN2.0B PHY interface to assist engineers in board-level design with an optimal resource mix and to reduce system costs.
As industry-leading 5V MCUs, the GD32F170/190 series MCUs come with chips having excellent anti-interference performance and ESD level. For their powerful capability of addressing EM noise, they are especially suitable for applications in a rigorous electrical environment. Their chip-grade ESD can reach 7KV in the human-body model and 1KV in the device model, well exceeding industry safety standards and reducing needs for external circuit protection components. Besides, GigaDevice provides a hardware fault-tolerant design, self-check program, and software testing library, which help users to meet IEC 60730 B certification requirements so that they can research and develop more durable and reliable products.
