HY16F3981 High-Precision Mixed Signal Micro Controller 4x32~ 6x30 LCD Driver 32-bit Low Power Micro Controller 21-bit ENOB ΣΔADC 64KB Flash ROM User's Guide
■The HY16F3981 is a low-power and high-precision mixed signal microcontroller (MCU) with LCD driver (Liquid Crystal Display), and is applicable to perform high-precision measurement and control; besides, the controller can work in a wide voltage range (2.2V-3.6V) and the clock of the controller canbe up to 16MHz; further, the controller has a built-in 64kbyte embedded Flash ROM and a 8kbyte SRAM. The HY16F3981 products integrate a high-precision 24-bit ΣΔ A/D converter, Rail-to-Rail OPAMP, 12-bit Resistance Ladder, Hardware RTC; moreover, the HY16F3981 products provide high-performance peripheral interfaces, such as the UART, SPI, I2C, GPIO and built-in power management system, etc., and support low-voltage detection and multiple peripheral interface wake-up functions. The HY16F3981 products are of low voltage, low power, low stand-by current, high integrity and high efficient operation, and support the 32-bit micro controller of the C development platform. Therefore, the HY16F3981 products can provide various resources for designers to designa low-current and low-cost mixed signal processing system.
The analog front-end circuit controller includes a 12-bit resistance ladder, a Rail-to-Rail OPAMP. In particular, 12-bit resistance ladderhas monotonicity, which is a step resistor, and the least significant bit (LSB) is close to 200ohm and the resistor has the low-temperature coefficient. The Rail-to-Rail OPAMP has an input network, which is applicable for the differential analog circuit configuration, such as integrator, current-to-voltage converter, programmable gain amplifier and successive approximation A/D converter.
The 24 bits A/D converter with extremely low noise is embedded. Its maximal output rate is 15KSPS, its ENOB (Effective number of bit) is 21, and its minimal resolvable signalis 1.1uV RMS Noise (Root-Mean-Square). ADC front-end built-in instrumentation amplifier IA, Maximum input magnification up to 256x magnification.
The power management provides selectable analogous regulating voltage, which can serve as reference voltage source or the power supply of a transducer. The working power source of the core of the CPU is also provided by the internal linear stabilized power supply. 64Kbyte embedded Flash ROM can be used to execute programs or store data; the data can be still stored into the Flash ROM even if the Flash ROM is executing a program. A built-in 8kbyte SRAM is provided for the system to use.
The core of the 32-bit high-performance mixed signal micro controller can execute an instruction during each clock cycle, which can be up to 16MIPS (Millions of Instructions per Second) and conform to low power consumption indicator. HYCON Technology provides convenient programming tools for users to write programs by C/C++ language or assembly language in the development platform. The chip has the circuit simulation function and provides a good environment for troubleshooting. The chip can work in 2.2V to 3.6V and -40°C to 85°C.
