Instructions for using the 8-bit OTP IO type single-chip microcontroller of the PADAUK PMS15B/PMS150G series
General OTP series
It is not recommended to be used in applications with AC resistance and capacitance step-down power supply or high EFT requirements
Operating temperature range: -40 °C ~ 85 °C


Series Program memory Data memory (byte) Maximum number of IO
PMS150G 1KW 64 6
PMS150B 0.5KW 64 6
PMS150G is almost the same as PMS150C.

During the programming period, the PMS150G PADAUK single-chip microcontroller uses a lower voltage o(图1)

Differences:
During programming, PMS150G uses a lower voltage on PA5, but uses a higher voltage than PMS150C on VCC.
When using the official Padauk programmer for programming, PMS150G requires a newer minimum hardware version (PDK5S-P003) than PMS150C (PDK3S-P002).
PMS150G can operate at 1.8V, while PMS150C requires at least 2.0V.
PMS150G requires more power when operating at a frequency of about 60 kHz (22 µA versus 13 µA).
Compared to PMS150C, PMS150G can drive and absorb more current on the I/O line.
PMS150G takes more time from power-on to start up.
The maximum clock of PMS150G is 2 MHz, while the maximum clock of PMS150C is 8 MHz.

PMS150G CPU feature application read/write examples
PMS15B/PMS150G series 8-bit OTP IO type single-chip microcontroller read/write examples, since your PMS150G has additional factory value @0x3f5, you should exclude this term and change ==>.exclude_code_start = 0x3F5, then it should not complain about "non-blank" IC.

Pin buffer hardware diagram. All IO pins of PMS15B/PMS150G can be set as input or output through the data register (pa), control register (pac), weak pull-up resistor (paph), and weak pull-down resistor (papl). Each IO pin can be independently configured with different functions; all these pin settings have Schmitt trigger input buffers and CMOS output drive potential levels. When these pins are at low output potential, the weak pull-up/pull-down resistors will be automatically turned off. When the upper/pull-down resistors are turned on simultaneously, the pull-down resistor will be automatically turned off. If you want to read the potential state on the port, it must be set to input mode first; in output mode, the data read is the value of the data register.

PMS150G burning knowledge
Application scope: PMS150G


  1. Preface
    For the PMS150G chip when burning in the semi-automatic machine, its burning process may be interfered by the semi-automatic machine or other work noise, which in turn causes the burning yield to decrease, or even the IC to be burned out. This APN provides improvement countermeasures.


The burning of PMS150G must use PDK5S-P-003 or PDK5S-P-003B. For the standard IC of SOP8, the burning method is exactly the same as PMS150C-S08. But for the package of SOT23-6, burning becomes more troublesome. The reason is that PDK5S-P-003 or PDK5S-P-003B needs to do pin testing on the IC during burning. Without making any declaration, the burner also does not know which specific IC needs to be burned, which will cause that when only the few burning pins are connected, there is a great chance that the IC cannot be burned.


  1. Description and improvement countermeasures
    Taking PMS150G-S08 as an example, to improve the stability and reliability of IC batch burning, before burning, please string a 100Ω resistor on the PA5 pin of JP2 behind the Writer. The connection method refers to Figure 1:

During the programming period, the PMS150G PADAUK single-chip microcontroller uses a lower voltage o(图4)

If burning the IC of the U06 package, please string a 100Ω resistor at the PA5 pin of JP7, and the connection method is shown in Figure 2 as follows:
