Programming the Flash
Atmel’s ATtiny28 offers 2K bytes of Flash program memory.
The ATtiny28 is shipped with the on-chip Flash program memory array in the erased
state (i.e., contents = $FF) and ready to be programmed. This device supports a high-
voltage (12V) parallel programming mode. Only minor currents (<1mA) are drawn from
the +12V pin during programming.
The program memory array in the ATtiny28 is programmed byte-by-byte. During pro-
gramming, the supply voltage must be in accordance with Table 21.
Parallel Programming
This section describes how to parallel program and verify Flash program memory, Lock
bits and Fuse bits in the ATtiny28.
Signal Names
In this section, some pins of the ATtiny28 are referenced by signal names describing
their function during parallel programming. See Figure 37 and Table 22. Pins not
described in Table 22 are referenced by pin name.
The XA1/XA0 pins determine the action executed when the XTAL1 pin is given a posi-
tive pulse. The coding is shown in Table 23.
When pulsing WR or OE, the command loaded determines the action executed. The
command is a byte where the different bits are assigned functions, as shown in Table
