The Parallax SX48BD is a member of the SX family of configurable communications controllers.

The Parallax SX48BD-G is a RISC architecture, high-speed microcontroller with expanded flash program memory, in-system programming and debugging capability. Operating at frequencies up to 75 MHz with an optimized single-cycle instruction set, developers can implement real-time functions as software modules. Common examples include communication interfaces (I2C, SPI, UARTs), frequency generation and measurement, PWM, and sigma-delta A/D.

The on-chip functions of the SX48BD-G include two general-purpose 16-bit timers, an analog comparator, watchdog timer, a power-save mode with wakeup capability, a configurable internal oscillator and high-current outputs; the SX48BD-G is typically used in production and manufacturing for projects requiring lots of I/O.   

Key Features:

•  262 bytes of RAM for speed
• 4KB of EEPROM for programming
• 36 I/O pins, enough for most applications
• Up to 75 MIPS for speed
• Internal oscillator (32 kHz to 4 MHz)
• Package: 48-pin TQFP
