SX48BD/SX52BD
Configurable munications Controllers with EE/Flash Program Memory, In-System Programming Capability, and On-Chip Debug
PRODUCT OVERVIEW
Introduction
On-chip functions include two 16-bit timers with 8-bit prescalers supporting different operating modes (PWM, simultaneous PWM/capture, and external event counter), a general-purpose 8-bit timer with prescaler, an analog parator, a brown-out detector, 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. The SX48BD and SX52BD are functionally the same, except for the package type and pinout. The SX48BD has four fewer pins and has only four rather than eight I/O pins for Port A.
The Ubi SX48BD/SX52BD are members of the SX family of configurable munications controllers fabricated in an advanced CMOS process technology. The advanced process, bined with a RISC-based architecture, allows high-speed putation, flexible I/O control, and efficient data manipulation. Throughput is enhanced by operating the device at frequencies up to 75 MHz and by optimizing the instruction set to include mostly single-cycle instructions. In addition, the SX architecture is deterministic and totally reprogramable. The unique bination of these characteristics enables the device to implement hard real-time functions as software modules (Virtual Peripheral™) to replace traditional hardware functions.
