PFS122
8bit MTP MCU with 12-bit R-Type ADC
9.2.8. Programming Writing
Please use PDK5S-P-003 to program. PDK3S-P-002 or older versions do not support programming PFS122.
Jumper connection: Please follow the instruction inside the writer software to connect the jumper.
Please select the following program mode according to the actual situation.
Normal Programming Mode
Range of application:
Single-Chip-Package IC with programming at the writer IC socket or on the handler.
Multi-Chip-Package(MCP) with PFS122. Be sure its connected IC and devices will not be damaged by
the following voltages, and will not clam the following voltages.
The voltage conditions in normal programming mode:
(1) VDD is 7.5V, and the maximum supply current is up to about 20mA.
(2) PA5 is 5.5V.
(3) The voltages of other program pins (except GND) are the same as VDD.
Important Cautions：
You MUST follow the instructions on APN004 and APN011 for programming IC on the handler.
Connecting a 0.01uF capacitor between VDD and GND at the handler port to the IC is always
good for suppressing disturbance. But please DO NOT connect with ＞0.01uF capacitor,
otherwise, programming mode may be fail.
Limited-Voltage Programming Mode
Range of application:
On-Board writing. Its peripheral circuits and devices will not be damaged by the following voltages, and
will not clam the following voltages. Please refer to On-Board Writing for more details.
Multi-Chip-Package(MCP) with PFS122. Please be sure that its connected IC and devices will not be
damaged by the following voltages, and will not clam the following voltages.
The voltage conditions in Limited-Voltage programming mode:
(1) VDD is 5.0V, and the maximum supply current is up to about 20mA.
(2) PA5 is 5.0V.
(3) The voltage of other program pins (except GND) is the same as VDD.
Please select "MTP On-Board VDD Limitation" or "On-Board Program" on the writer screen to enable the
limited-voltage programming mode. (Please refer to the file of Writer “PDK5S-P-003 UM”).
