External clock input Low frequency (128kHz) Internal Resistor & Capacitor oscillator (LIRC)
- Analog Peripherals
- 12-bit 200ksps single-ended ADC with (14+3) analog input channel
- 1 set of DAC with 8-bit resolution
-
Two comparators with 2mV input offset voltage (typ.) and 200ns response time (typ.), one comparator among them can be used as operational amplifier.
Timer/Counter/window/buzzer/PWM/PDO (programmable divider output) modes, respectively. Timer 1 and Timer 2 can be cascaded to one 16-bit counter/timer - Internal voltage references: 4.096V/3.072V/2.560V/2.048V (1LSB: 1mV/0.75mV/0.625mV/0.5mV)
- On-chip Low-voltage detect/reset (LVDR): (2.8/2.9V) or (3.3/3.4V) ±0.1V @ -40°C~85°C
- Digital Peripherals
- 1-set I2C, share pin with Elan’s UART
- 2-set UART: 8051’s own UART and the other one is Elan’s UART which shares pin with I2C.
- 18 I/O pins. Each of them supports pull-high, pull-low, normal drive/sink, high drive/sink control functions
- Two standard 8051 16-bit timer/counter (TC0, TC1) with four operation modes (Mode 0~3)
- Two general-purpose 8-bit timers with seven modes including Timer, Counter, Capture, Window, Buzzer, PWM and PDO (Programmable Divider Output, TC3 and TC4)
- One set of complementary PWM, /PWM with 16-bit resolution.
- Packages
