SX18AC
/ SX20AC / SX28AC
High-Performance 8-Bit Microcontrollers with EE/Flash Program
Memory and In-System Programming Capability
1.0
1.1
The SX18AC, SX20AC, and SX28AC are members of
the SX family of high-performance 8-bit microcontrollers
fabricated in an advanced CMOS process technology.
The advanced process, combined with a RISC-based
architecture, allows high-speed computation, flexible I/O
control, and efficient data manipulation. Throughput is
enhanced by operating the device at frequencies up to 50
MHz and by optimizing the instruction set to include
mostly single-cycle instructions.
On-chip functions include a general-purpose 8-bit timer
with prescaler, an analog comparator, a brown-out detec-
tor, a watchdog timer, a power-save mode with multi-
source wakeup capability, an internal R/C oscillator,
user-selectable clock modes, and high-current outputs.
