HT68F2420 HT68F2420 High Precision HIRC Flash MCU High Precision HIRC Flash MCU D.C. Characteristics
For data in the following tables, note that factors such as oscillator type, operating voltage, operating frequency, pin load conditions, temperature and program instruction type, etc., can all exert an influence on the measured values.
Operating Voltage Characteristics
Ta=25°C Typical
Symbol Parameter Test Conditions Min. Typ. Max. Unit
Operating Voltage – HIRC f V SYS=4MHz 1.8 — 5.5 V DD Operating Voltage – LIRC fSYS=32kHz 1.8 — 5.5 V
Operating Current Characteristics
Ta=25°C Typical
Test Conditions Symbol Operating Mode Min. Typ. Max. Unit VDD Conditions
3V — 1.0 2.0 FAST Mode – HIRC fSYS=4MHz mA 5V — 2.0 3.0 IDD 3V — 10 20 SLOW Mode – LIRC fSYS=32kHz μA 5V — 30 50 Note: When using the characteristic table data, the following notes should be taken into consideration: 1. Any digital inputs are setup in a non-floating condition. 2. All measurements are taken under conditions of no load and with all peripherals in an off state. 3. There are no DC current paths. 4. All Operating Current values are measured using a continuous NOP instruction program loop.
Standby Current Characteristics
Ta=25°C Typical
Test Conditions Max. Symbol Standby Mode Typ. Max. Unit VDD Conditions 85°C
3V 0.2 0.8 1 WDT off μA 5V 0.5 1 1.2 SLEEP Mode 3V 3.0 5.0 6.0 WDT on μA 5V 5.0 10 12 ISTB 3V 3.0 5.0 6.0 IDLE0 Mode – LIRC fSUB on μA 5V 5.0 10 12 3V 0.8 1.6 1.9 IDLE1 Mode – HIRC fSUB on, fSYS=4MHz mA 5V 1.0 2.0 2.4 Note: When using the characteristic table data, the following notes should be taken into consideration: 1. Any digital inputs are setup in a non-floating condition. 2. All measurements are taken under conditions of no load and with all peripherals in an off state. 3. There are no DC current paths. 4. All Standby Current values are taken after a HALT instruction execution thus stopping all instruction execution.
