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.
* 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
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.
APPLICATIONS
* Remote control with learning
function
* Preset universal remote control
