MCRF355
4.0
MCRF355 is a reprogrammable device in Contact
mode. The device has 154 bits of reprogrammable
memory. It can be programmed in the following proce-
dure. (A programmer, part number PG103003, is avail-
able from Microchip). Developer kits, DV103003 and
DV103006, also include contact programmers.
4.1
Programming logic is enabled by applying power to the
device and clocking the device via the CLK pad while
loading the mode code via the V
Examples 4-1 through 4-4 for test definitions). Both the
CLK and the V
resistors.
