SINGLE CHIP COMPUTER USING CH552E

Описание: SINGLE CHIP COMPUTER RUNNING BASIC-52 USING CH552E AT 24MHz.

WS2812B LEDs controlled by CH552E.

Less than $1 BOM cost.
World's smallest, cheapest and most powerful Single Chip Computer.
Internal 24MHz oscillator.
No external ROM required. Internal FLASH.
No external RAM required. Internal RAM.
No external crystal or oscillator required.
No external latches or buffers required.
Serial USB TO TTL implemented with CH551G.
Enhanced 8051 core 10x faster than Intel.
ASCIIART running with BASIC-52 at 24MHz within 24.78 seconds.
No EXTERNAL device programmer required.
Flash programming using WCHISPTOOL via USB.
Very low components count and BOM cost.
CH554, CH558 and CH559 can be used with increased memory and number of IO pins.
CH558 and CH559 can be operated at 48MHz.
CH552E and CH55E available in MSOP10.
Runs BASIC-52 V1.31 seamlessly.
Apart from BASIC-52, user can program using SDCC or KEIL ETC.

CH552G BASIC-52 source code and HEX file can be downloaded from
