DESCRIPTIONS
The S1C33L26 is a 32-bit application specific RISC controller that features extensive peripheral circuits such as an
enhanced drawing graphics module, GPIO ports, serial interface modules, a USB module, PWM generators, and an A/D
converter. It is suitable for applications that require a high-resolution LCD display, e.g. control panels on OA/FA equipment
and intelligent remote controllers.
The S1C33L26 incorporates an LCD controller and VRAM supporting four-level gray scale QVGA display in single-chip.
Adding an external SDRAM expands this capability into a higher resolution and with more displayable colors (e.g., 64K-color
VGA display). An LCD driver interface with DMA function is also implemented allowing efficient data transfer to LCD modules
that include a built-in VRAM LCD driver. In addition, the embedded Graphics Engine (GE) provides rich graphic features,
such as drawing functions for dots, straight lines, triangles, rectangles, and circles, resizing, and rotation that can be used
simply by calling commands.
The GE also supports drawing of lossless compressed image data; this makes it possible to reduce CPU load and image
data ROM size.
As for DSP functions, a 32-bit × 32-bit multiplier (MUL) and a 16-bit ÷ 16-bit divider (DIV) are implemented. These functions
help reduce CPU load for ADPCM audio data playback processing. Also the embedded I2S interface module is used to
connect an external audio DAC.
The S1C33L26 has adopted the EPSON SoC (System on Chip) design technology using 0.18
μm
low power CMOS process
to install these features.
