S1C33L05
32-bit Single Chip Microcomputer
■ DESCRIPTION
● 32-bit S1C33000 RISC Core
● Low Power
● Multiply Accumulation
● Built-in 16K-byte RAM
● 10-bit ADC
● Built-in LCD Controller
● Built-in USB1.1 Function Controller
● Built-in SDRAM Controller
The S1C33L05 is a Seiko Epson original 32-bit microcomputer that features high speed, low power consump-
tion, and low-voltage operation. The S1C33L05 consists of an S1C33000 32-bit RISC type CPU as its core,
peripheral circuits including a bus control unit, DMA controller, interrupt controller, timers, serial interface with
FIFO, A/D converter, a color STN LCD controller that supports 64K color display, SDRAM controller, USB1.1
function controller, sequential ROM interface, MMC (SPI mode) interface and NAND flash interface, and also an
embedded RAM. Two oscillation circuits and a PLL are also included, supporting advanced operation, power-
saving operation, and high-performance realtime clock functions. The S1C33L05 is ideal for portable products
that require high-speed data processing. Especially it is suitable for the application processor embedded in
PDAs, electronic dictionary and e-Book readers.
