NOTICE: This document contains information on

products in the sampling and initial production

phases of development. The specifications are

subject to change without notice. Verify with your

local Intel sales office that you have the latest

datasheet before finalizing a design.

OPERATING CONDITIONS†

TA (Ambient Temperature Under Bias):

Commercial ........................................................ -0°C to +70°C

VCC / VCCP (Digital Supply Voltage) ................ 4.40 V to 5.25 V

VSS / VSSP............................................................................ 0 V

AVCC (Analog Supply Voltage) ...................... 4.40 V to 5.25 V

FOSC ............................................................................. 12 MHz

† WARNING: Stressing the device beyond the

“Absolute Maximum Ratings” may cause

permanent damage. These are stress ratings only.

Operation beyond the “Operating Conditions” is not

recommended and extended exposure beyond the

“Operating Conditions” may affect device

reliability.

NOTE: Maximum power dissipation is based on

package heat-transfer limitations, not device

power consumption.

NOTES:

1. Other PLLSELx combinations are not valid.

2. The sampling rate is four times the USB rate.

3. The AC timing specification (Table 16) defines the following symbol: CPU frequency

= FCLK = 1/TCLK.

4. The 8x930Hx CPU and peripheral frequency is 3 MHz (low clock mode) until the LC

bit in PCON is cleared by user firmware.

5. When the CPU is operating in low clock mode (3 MHz), 1 state equals 4 Tosc.
