New, genuine Parallax SX28AC/DP Microcontrollers These microcontrollers have been discontinued and are no longer available. Once they're gone, they're gone! They are still widely supported, with sites like sxlist.com dedicated to the SX line. There is also the SX/B compiler (free!), which makes programming easy in BASIC language. I can provide links if you ask, eBay won't allow them in this listing. 75 MIPS Performance SX20AC/SX28AC: DC - 75 MHz SX20AC/SX28AC: as low as 13.3 ns instruction cycle, 39.9 ns internal interrupt response 1 instruction per clock for most instructions (skips require 2 clocks, branches require 3 clocks, IREAD requires 4) EE/FLASH Program Memory and SRAM Data Memory Access time of <13.3 ns provides single cycle access EE/Flash rated for >10,000 rewrite cycles 2048 Words EE/Flash program memory 136x8 bits SRAM data memory CPU Features Compact, RISC-like instruction set All non-branch instructions are single cycle Eight-level push/pop hardware stack for subroutine operation Fast table lookup capability through run-time readable code (IREAD instruction) Totally predictable program execution rate for precise real-time applications Fast and Deterministic Interrupt Jitter-free 3-cycle internal interrupt response Hardware context save/restore of key resources such as PC, W, STATUS, and FSR within the 3-cycle interrupt response time External wakeup/interrupt capability on Port B (8 pins) Flexible I/O All port pins individually programmable as I/O Inputs are TTL or CMOS level selectable All pins have selectable internal pull-ups Selectable Schmitt Trigger inputs on Ports B and C All output pins capable of sourcing/sinking 30 mA Port A outputs have symmetrical drive Analog comparator support on Port B (RB0 OUT, RB1 IN-, RB2 IN+) Selectable I/O operation synchronous to the oscillator clock Hardware Peripheral Features One 8-bit Real Time Clock/Counter (RTCC) with programmable 8-bit prescaler Watchdog Timer (shares the RTCC prescaler) Analog comparator Brown-out detector Multi-Input Wakeup logic on 8 pins Internal RC oscillator with configurable rate from 31.25 kHz to 4 MHz Power-On-Reset Programming and Debugging Support On-chip in-system serial programming support via the oscillator pins On-chip in-system debugging support logic Real-time emulation, full program debug, and integrated development environment offered by the Parallax SX-Key® programming device The language options available: Parallax Assembly; Parallax SX/B (BASIC); and CCS SX/C Software Support Native assembly instruction set Expanded assembly instruction set available in the SASM assembler of the Parallax SX-Key IDE Parallax SX/B compiler (BASIC) Several “C” compliers available from third-party vendors
