Notes:
1. Active Current measure using typical code loop - Digital Supply Current depends upon the particular code
being executed. Digital Supply Current depends on the particular code being executed. The values in this
table are obtained with the CPU executing a mix of instructions in two loops: djnz R1, $, followed by a loop
that accesses an SFR, and moves data around using the CPU (between accumulator and b-register). The
supply current will vary slightly based on the physical location of this code in flash. As described in the Flash
Memory chapter, it is best to align the jump addresses with a flash word address (byte location /4), to
minimize flash accesses and power consumption.
2. Includes oscillator and regulator supply current.
3. Based on device characterization data; Not production tested.
4. Measured with one-shot enabled.
5. Low-Power Idle mode current measured with CLKMODE = 0x04, PCON = 0x01, and PCLKEN = 0x0F.
6. Using SmaRTClock osillator with external 32.768 kHz CMOS clock. Does not include crystal bias current.
7. Low-Power Idle mode current measured with CLKMODE = 0x04, PCON = 0x01, and PCLKEN = 0x00.
