1755C

1755C is a 32‑bit microcontroller model produced by TechNova Semiconductors, introduced in 2022 for embedded control and Internet of Things applications. The device is offered in compact packages suitable for space-constrained designs and is often used in wearables, sensors, and small consumer electronics. The 1755C family emphasizes a balance of performance, low power, and ease of development.

The core design centers on a 32-bit ARM Cortex-M0+ processor clocked up to 48 MHz, with on‑chip memory consisting of 128 KB of flash and 16 KB of RAM. A cryptographic engine provides hardware-accelerated security features, including AES‑128. The MCU incorporates a range of peripherals common to low‑power systems: two SPI interfaces, two I2C buses, one UART, and USB 2.0 full‑speed for device communications. An eight‑channel, 12‑bit ADC and several general-purpose PWM outputs support sensor interfacing and motor control. The device operates from a supply voltage range of 1.8 to 3.3 volts and includes multiple power modes to optimize energy use in battery-powered designs.

Development and tooling are supported through GCC and CMSIS ecosystems, with TechNova’s own TechIDE and OpenOCD compatibility for debugging via SWD. An evaluation board and baseline firmware examples are provided to accelerate prototyping and deployment.

Variants of 1755C include the 1755C-20 and 1755C-48, configured for 20 MHz and 48 MHz operation respectively, along with a low‑power LP variant and USB‑enhanced versions. The 1755C line is positioned as an accessible option for compact, energy-efficient embedded projects.
