ATtiny43U
19.3.1
Signature Bytes
All Atmel microcontrollers have a three-byte signature code which identifies the device. This
code can be read in both serial and High-voltage Programming mode, also when the device is
locked.
Signature bytes can also be read by the device firmware. See section “Reading the Fuse and
The three signature bytes reside in a separate address space called the device signature imprint
table. The signature data for ATtiny43U is given in Table 19-7.
19.3.2
Calibration Byte
The device signature imprint table of ATtiny43U contains one byte of calibration data for the
internal oscillator, as shown in Table 19-6 on page 143. During reset, this byte is automatically
written into the OSCCAL register to ensure correct frequency of the calibrated oscillator.
Calibration bytes can also be read by the device firmware. See section “Reading the Fuse and

Parallel Programming Parameters, Pin Mapping, and Commands
This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATtiny43U. Pulses are assumed to be at
least 250 ns unless otherwise noted.
19.5.1
Signal Names
In this section, some pins of the ATtiny43U are referenced by signal names describing their
functionality during parallel programming, see Figure 19-1 and Table 19-10. Pins not described
in the following table are referenced by pin names.
