The S1C33L19 is a cost-effective, high-performance 32-bit RISC controller designed specifically for graphic
display applications. It incorporates LCD display functions and JPEG image processing for electronic
devices requiring LCD display of images, such as photo viewers and other compact image display units,
home intercoms and other home electronic devices, as well as operating panels incorporated into various
office equipment.
The JPEG image processing function uses an internal hardware accelerator for high-load JPEG processing
to achieve faster processing than software processing alone. It is provided as an easy-to-use JPEG
decoder/encoder API with complex controls handled internally, allowing easy interfacing with applications for
easy, high-speed enlargement and compression of JPEG image data, including photographs, improved
application display capabilities, and smaller data sizes.
Peripheral circuits and pin layout are completely forward-compatible with the S1C33L17, enabling use with
applications that rely on ADC functions and a wide range of serial interfaces, including numerous
general-purpose input/output ports, powerful PWM timer/counter, and USB-FS device controller.
The S1C33L19 consists of a 32-bit RISC CPU core, JPEG decoder/encoder, general-purpose DMA
controller, USB-FS device controller, PWM control timer/counter, several interfaces (IrDA1.0, SIO including
