NOTES:

1. After a reset, the microcontroller fetches its first instruction from 2080H.

2. The content or function of these locations may change in future microcontroller revisions, in which

case a program that relies on a location in this range might not function properly.

5.0 ELECTRICAL CHARACTERISTICS

ABSOLUTE MAXIMUM RATINGS

Storage Temperature .................................. –60°C to +150° C

Voltage from VPP or EA# to VSS or ANGND... –0.5V to +13.0 V

Voltage from any other pin to VSS or ANGND ... –0.5V to +7.0V

Power Dissipation .......................................................... 0.5 W

OPERATING CONDITIONS†

TA (Ambient Temperature Under Bias)...........–40°C to +125°C

VCC (Digital Supply Voltage) ............................ 4.50V to 5.50V

VREF (Analog Supply Voltage)............................ 4.50V to 5.50V

FXTAL1 (Input Frequency):

- PLL in 2x mode............................ 4 MHz to 10 MHz

- PLL in 1x mode............................ 8 MHz to 20 MHz

Notes

1. ANGND and VSS should be nominally at the same potential.

2. VREF should not exceed VCC by more than 0.5V.

NOTICE: This document contains information

on products in the design phase of develop-

ment. Do not finalize a design with this infor-

mation. Revised information will be published

when the product is available. Verify with your

local Intel sales office that you have the latest

datasheet before finalizing a design.

†WARNING: Stressing the device beyond the

“Absolute Maximum Ratings” may cause per-

manent damage. These are stress ratings

only. Operation beyond the “Operating Condi-

tions” is not recommended and extended

exposure beyond the “Operating Conditions”

may affect device

reliability.
