■ DESCRIPTIONS
The S1C33401 is a 32-bit RISC-type microcomputer originally developed for embedded applications by Seiko Epson.
The S1C33401 is built around the C33 ADV core block that includes the CPU, MMU, cache, and modules that allow
various external memory and I/O devices to be connected directly, and incorporates a bus block that includes the DMA
controller and other control units. In addition to these primary units, the S1C33401 incorporates a basic peripheral circuit
block that includes an interrupt controller, timers, serial interfaces, card interfaces, input/output ports, and A/D
converter, and an extended peripheral circuit block that includes a chip ID register, RTC, and other components.
The S1C33401 is manufactured by a 0.18 μm fine-pattern CMOS process, backed by sophisticated clock control
functions, and can operate at higher speed with less power than ever before. In addition to its use as an embedded-type
processor in various portable systems, the S1C33401 features a built-in C33 ADV CPU to provide enhanced functionality
for multimedia support while retaining upward compatibility with the conventional C33 STD CPU, making it an ideal
solution to the requirements of mobile multimedia applications.

■ FEATURES
CORE
● CPU
• Original Seiko Epson 32-bit RISC-type CPU – C33 ADV
• Internal 32-bit data processing
• 4GB address space
• Powerful instruction set
- Code length:
16 bits per instruction
- Number of instructions: 164
- Main instructions executable in 1 cycle (including immediate-extended instructions, each consisting of two to three
instructions)
- 15.15 ns per instruction (when operating at 66 MHz, max.)
• Multimedia support functions
- Built-in 32-bit × 16-bit multiplier
- 16 × 16, 32 × 16 and 32 × 32-bit multiplication
- 16 × 16, 32 × 16 and 32 × 32-bit multiply-accumulate operations
- Repeated execution by loop and repeat instructions
- Rounding to minimum/maximum values by saturation instruction
- ALU instruction execution with post-shift
● High-speed Bus Control Unit (HBCU)
• Controls memory access by the CPU by dividing 4GB logical space into eight 512MB blocks.
• Manages MMU, CCU, and ASID processing in each block.
• Capable of multiplexing logical space using ASID and mirroring physical space.
• Can simultaneously process A0RAM data read/write operations and instruction fetching from cache.
