HT32F49153/HT32F49163

General Information

The HT32F49153/HT32F49163 devices are based on the high-performance Arm^® Cortex^®-M4 32-bit RISC core operating at a frequency of up to 150 MHz. The Cortex^®-M4 core features a Floating Point Unit (FPU) single precision supporting all Arm^® single-precision data processing instructions and data types. It also implements a full set of DSP instructions and a Memory Protection Unit (MPU) that enhances application security.

The devices incorporate high-speed on-chip memories, including up to 256 Kbytes of Flash memory, 48 Kbytes of SRAM, and 20 Kbytes of boot memory that can be used as a Bootloader or as a general instruction/data memory (one-time-configurable) to achieve the maximum of 256+20 Kbytes. Any block of the embedded Flash memory can be protected by the “sLib” (security library), functioning as a security area with code-executable only. In addition, the devices include a highlevel memory extension: an external memory controller (XMC).

The devices offer one 12-bit ADC, two 12-bit DACs, eight general-purpose 16-bit timers plus one general-purpose 32-bit timer, two basic timers, one advanced timer and one low-power ERTC. It also features standard and advanced communication interfaces: up to three I²Cs, three SPIs (multiplexed as I²Ss), eight USARTs, two CANs, an OTGFS, and infrared transmitter.

The devices operate in the -40 to +105 °C temperature range, from a 2.4 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power application.

The devices are supplied in different package types. The entire HT32F49153/HT32F49163 series of devices are pin-to-pin, software and functionally compatible with each other, except that the configurations of peripherals are not fully identical depending on the package types.
