{ On-chip power-on clear (POC) circuit and low voltage detector (LVI)
{ On-chip watchdog timer (operable on internal low-speed internal oscillator clock)
{ I/O ports: 17
{ Timer: 4 channels
• 16-bit timer/event counter: 1 channel
• 8-bit timer:
2 channels
• Watchdog timer:
1 channel
{ Serial interface: UART (LIN (Local Interconnect Network) bus supported) 1 channel
{ 10-bit resolution A/D converter: 4 channels
{ Supply voltage: VDD = 2.0 to 5.5 V^Note
{ Operating temperature range: TA = −40 to +85°C
Note Use this product in a voltage range of 2.2 to 5.5 V because the detection voltage (VPOC) of the power-on
clear (POC) circuit is 2.1 V ±0.1 V.
