Configurable Communications Controllers with EE/Flash Program
Memory, In-System Programming Capability and On-Chip Debug
1.0
1.1
The Scenix SX family of configurable communications
controllers are fabricated in an advanced CMOS process
technology. The advanced process, combined with a
RISC-based architecture, allows high-speed computa-
tion, flexible I/O control, and efficient data manipulation.
Throughput is enhanced by operating the device at fre-
quencies up to 50/75 MHz and by optimizing the instruc-
tion set to include mostly single-cycle instructions. In
addition, the SX architecture is deterministic and totally
reprogramable. The unique combination of these charac-
PRODUCT OVERVIEW
Introduction
teristics enables the device to implement hard real-time
functions as software modules (Virtual Peripheral) to
replace traditional hardware functions.
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.
