NM1234D Datasheet | Nuvoton Technology

DESCRIPTION The Nu Micro® NM1230 series 32-bit microcontrollers are embedded with ARM® Cortex® -M0 core for industrial applications which need high performance, high integration, and low cost. The Cortex® M0 is the newest ARM® embedded processor with 32-bit performance at a cost equivalent to the traditional 8-bit microcontroller. The NM1230 series can run up to 48(72) MHz and operate at 2.2V(3.3V) ~ 5.5V, -40℃ ~ 105℃, and thus can support a variety of industrial control applications which need high CPU performance. The NM1230 offers 64 Kbytes embedded program Flash, size configurable Data Flash (shared with program flash), 7.5 Kbytes Flash for the ISP, 1.5 Kbytes SPROM for security, and 16Kbytes SRAM. Many system level peripheral functions, such as I/O Port, Timer, UART, SPI, I2C, PWM, ADC, OP, PGA, Watchdog Timer, Analog parator and Brown-out Detector, have been incorporated into the NM1230 to reduce ponent count, board space and system cost. These useful functions make the NM1230 powerful for a wide range of applications. Additionally, the NM1230 series is equipped with ISP (In-System Programming) and ICP (In-Circuit Programming) functions, which allow the user to update the program memory without removing the chip from the actual end product.
