SC51D01Fxx
REMOTE CONTROL WITH BUILT-IN FLASH AND
CODE SAMPLING FUNCTION
DESCRIPTIONS
SC51D01Fxx series is mainly used in remote controls with
learning function. It is based on Silan’s S51 8-bit MCU compliance
with standard MCS-51 instructions and has built-in large FLASH
program memory, infrared signal amplifier, and code
sampling/transmitting modules. Under the support of few periphery
components, these ICs can be easily used to make a remote
control with on-chip self-learning function, which will enable one
remote control to control all the devices related to TV sets.
FEATURES
* Compliance with standard MCS-51 instructions.
* Built-in 16K/32K/64K bytes FLASH program memory(can also
used as data memory).
* Built-in 4K bytes XRAM.
APPLICATIONS
* Integrate infrared signal amplifier.
* Integrate code sampling circuit which support code sampling
with carrier, and has 256 bytes receive buffer.
* Integrate code transmitting circuit whose carrier frequency and
* Remote control with learning
function
* Preset universal remote control
duty can be set flexibly and has 32 bytes send buffer.
* 8 keyboard input pins.
* Support in system program (ISP).
* Adopt CMOS technology, operating voltage is 2.2V-3.6V, and
quiescent current is less than 1μA.

SC51D01Fxx
[Function Description]
In standby mode, low level applied to any keyboard input port will make the chip reset and enter the
normal working mode; however, in normal working mode, input low level will not reset the chip.
General Purpose I/O Ports
[Brief]
SC51D01FxxA has PT1 and PT4 two groups of 10 general purpose I/O ports (GPIO); SC51D01FxxB
has PT1, PT3 and PT4 three groups of 14 GPIO. The structure and the manipulation of SC51D01Fxx
series’ GPIO are different from those of standard 8051.
[Structure Diagram]
Fig. 7– PT1 structure
Note: The structure of PT3 and PT4 is the same as that of PT1.
[Function Description]
Related with Fig. , the following takes PT1 for example to introduce the function of general purpose I/O
ports. The function of PT3 and PT4 is the same as that of PT1.
Configure the output mode of GPIO pins
The output mode of every GPIO pin can be configured as open-drain or pull-push mode, default is open-
drain. When PT1Ctrl[n]=0, no matter PT1Reg[n] output 1 or 0,P1 and N1 misfits are both off, and the output
mode corresponding to PT1n pin is open-drain; when PT1Ctrl[n]=1, the off/on of P1 and N1 is decided by
the output status of PT1Reg[n], and the output mode corresponding to PT1n pin is pull-push.
In pull-push mode, PT1Reg[n]=0 will turn P1 off, N1 on, and PT1n pin will connect to GND; PT1Reg[n]=1
will turn P1 on, N1 off, and PT1n pin will connect to VDD.
In open-drain mode, PTODCtrl[n]=0 of open-drain output register will turn N2 on, PT1n pin will connect to
GND;PTODCtrl[n]=1 will turn N2 off, PT1n pin is in high impedance. When the application system needs
many output ports connected to one physical wire (e.g. the scanning output wire of keyboard), those ports
must be in open-drain mode! In open-drain mode, the port needs to connect pull-up resistor to VDD or using
internal pull-up resistor(PT1PUCtrl[n]=0,P2 is on, PT1n is pulled-up to VDD via Rpu).
