ATtiny2313/V
2543C–AVR–12/03
Notes:
1. These options should only be used when not operating close to the maximum fre-
quency of the device, and only if frequency stability at start-up is not important for the
application. These options are not suitable for crystals.
2. These options are intended for use with ceramic resonators and will ensure fre-
quency stability at start-up. They can also be used with crystals when not operating
close to the maximum frequency of the device, and if frequency stability at start-up is
not important for the application.
Calibrated Internal RC
Oscillator
The calibrated internal RC Oscillator provides a fixed 8.0 MHz clock. The frequency is
nominal value at 3V and 25
°C. If 8 MHz frequency exceeds the specification of the
device (depends on V
CC), the CKDIV8 Fuse must be programmed in order to divide the
internal frequency by 8 during start-up. The device is shipped with the CKDIV8 Fuse
programmed. This clock may be selected as the system clock by programming the
CKSEL Fuses as shown in Table 6. If selected, it will operate with no external compo-
nents. During reset, hardware loads the calibration byte into the OSCCAL Register and
thereby automatically calibrates the RC Oscillator. At 3V and 25
°C, this calibration gives
a frequency within ± 10% of the nominal frequency. Using run-time calibration methods
as described in application notes available at www.atmel.com/avr it is possible to
achieve ± 2% accuracy at any given V
CC and Temperature. When this Oscillator is used
as the chip clock, the Watchdog Oscillator will still be used for the Watchdog Timer and
for the Reset Time-out. For more information on the pre-programmed calibration value,
see the section “Calibration Byte” on page 161.
Note:
1. The device is shipped with this option selected.
