DRPIC166X MCU, low-cost mixed with high performance
The good old fashioned PIC microcontrollers are finding their way into new applications like automotive, smartphones, gaming peripherals, audio devices and embedded solutions for eg innovative medical devices. Moreover, because the DRPIC166X has upward compatible architecture, it preserves investment in code development. And if it’s not enough, let’s just mention that DCD’s IP Core offers 1.3GHz virtual clock frequency and consumes just 37uW/MHz.The
The DRPIC166X soft core is software-compatible with the industry standard PIC 16XXX microcontrollers. DCD’s IP Core implements an enhanced Harvard architecture (separate instruction and data memories) with independent address and data buses.
The same, it’s 4 times faster compared to the standard architecture. The 14 bit program memory and 8-bit dual port data memory allow instruction fetch and data operations, to occur simultaneously. The advantage is that the instruction fetch and memory transfers can be overlapped, by multi stage pipeline, so that the next instruction can be fetched from program memory, while the current instruction is executed with data from the data memory – explains Hanke. Most instructions are executed within 1 system clock period, except the instructions which directly operate on PC (GOTO, CALL, RETURN) program counter. The pipeline is being cleared and subsequently refilled at additional one clock cycle.
The DRPIC166X Microcontroller fits perfectly in applications ranging from high-speed automotive and appliance motor control, to low-power, remote transmitters/receivers, pointing devices, telecom processors or consumer electronics. Built-in power save mode, makes this IP core perfect for applications, where the power consumption aspect is critical.
The DRPIC166X is delivered with fully automated testbench, complete set of tests and DoCDTM on-chip hardware debugger, allowing easy package validation, at each stage of SoC design flow.
