General Description ：
The YC1021 is a very low power, high
performance and highly integrated Bluetooth 4.1 BR/EDR + BLE + 2.4G
Proprietary triple-mode solution, designed for operation over the
2400MHz to 2483.5Mhz ISM frequency band.
YC1021 is manufactured using advanced 55nm CMOS low leakage process, which offers highest integration,
lowest power consumption, lowest leakage current and reduced BOM cost while simplifying the overall system design.
Rich peripherals including an 8 channel
general purpose ADC, power-on-reset (POR), Arithmetic Accelerators,
USB2.0, 3axis Q-decoder, ISO7816, UART/SPI/I2C and up to 32 GPIOs, which
further reduce overall system cost and size.
YC1021 operates with a power supply range
from 1.8 to 5.5V and has very low power consumption in both Tx and Rx
modes, enabling long lifetimes in battery-operated systems while
maintaining excellent RF performance. The device can enter an ultra low
power sleep mode in which the registers and retention memory content are retained while low power Oscillator and sleep timer is ON.
Different package from QFN4x4_32L(upto 17 GPIOs) to QFN7x7_56L (upto 32 GPIOs) is available.
