:link: Naming Scheme

Padauk’s µCs are usually named according to this scheme:

P{G,F,M}{C,S}nNN(c)

  • F: MTP (Flash)
  • G: MTP (Flash + EEPROM)

  • M: OTP

  • C: High ESD and high noise tolerance

  • S: Low ESD and low noise tolerance

  • n: Number of hardware threads (“FPPAs”)

  • NN: Part number suffix, numeric

  • (c): Optional part number suffix, alphabetic; possibly a revision code.

:link: XDM{F}{SSS} chips

XDM{F}{SSS} chips are a combination of regular Padauk µCs with additional hardware inside a single package. An overview of available chips can be found here. The naming scheme is XDM:

  • F: 1 = MOS, 2 = Power, 3 = Communication, 4 = Memory/Flash, 5 = drive (? Chinese name is 驱动)
  • SSS: Number to differentiate parts Below is a list of available chips and the included additional hardware:
Name Included Padauk µC Additional Hardware
XDM1101 PMS150C 2302 (2A NMOS)
XDM1102 PMS150C 2300 (3A NMOS)
XDM2101 PMS132B 78L05 (5V Regulator)
XDM2102 PMS150C 2300 (3A NMOS) + 4056 (Lithium Battery Charger)
XDM2801 PMS164 78L05 (5V Regulator)
XDM4101 PFS172 24C02 (2K EEPROM)
XDM4102 PMS132B 24C02 (2K EEPROM)
XDM4103 PMS152 24C02 (2K EEPROM)
XDM4104 PFS154 24C02 (2K EEPROM)
XDM4105 PFS173 24C02 (2K EEPROM)
XDM4106 PMS171 24C02 (2K EEPROM)
XDM4107 PMS134 24C02 (2K EEPROM)

:link: Oddities

As always, no rule is without exception, and we discovered or found references to a few odd µCs:

  • PES50N(c) No further information is known.

  • PGR431 No further information is known.

  • XN1{2,3}{1,2}0(c) No further information is known.

  • PDK22CNN(c) A lot of these were supported by older versions of Mini-C; since then support for all of them has been dropped.
    • NN: Part number suffix, numeric
    • (c): Optional part number suffic, alphabetic.

  • P201C{D,S}1{4,6}A Some of these were supported by older versions of Mini-C; since then support for all but one has been dropped.

  • P23{2,4}C(cnn) Many of these were supported by older versions of Mini-C; since then support for all but one has been dropped.

  • EV_2, ip5{d,c}, MCU371, MCU390, PDK82C1{2,3}, PDK_3S_EV, PDK_EV5, PDK82S_EV These are only known from Mini-C files. Nothing else is known about them.,

  • DF329, DF69, MCS11 These are missing from Mini-C and the catalog, but there are datasheets. All of them are pdk16 devies with 8 hardware threads.

  • DF319, DF339 These are missing from Mini-C and the catalog, but there are datasheets. However, the datsheets contain little information. These are probably pre-programmed OTP devices for use as motor controllers.
