PY32F003

Part: PY32F003 Series — Puya Semiconductor (Shanghai) Co., Ltd

Type: 32-bit ARM Cortex-M0+ Microcontrollers

Description: 32-bit ARM Cortex-M0+ microcontroller with embedded Flash and SRAM, supporting multiple clock sources and low-power modes.

Operating Conditions:

• Max clock frequency: 24 MHz

Key Specs:

Features:

• ARM Cortex-M0+ core
• Embedded Flash memory
• Embedded SRAM
• Boot mode
• Power-on reset (POR)/power-down reset (PDR)/brown-out reset (BOR)
• Programmable voltage detector (PVD)
• Sleep and Stop low-power modes
• High-speed external (HSE), high-speed internal (HSI), and low-speed internal (LSI) clock sources
• General-purpose I/Os (GPIO)

• Main Flash block: maximum 64 KBytes (16 k x 32 bits)
• Information block: 4 KBytes (1 k x 32 bits)
• Page size: 128 Bytes
• Sector size: 4 KBytes

The Flash control interface circuit features:

• Flash write and erase
• Read protection
• Write protection

After reset (SYSRESETn or PORESETn), the pins used for the SW-DP are assigned as dedicated pins which are immediately usable by the debugger host.

However, the MCU offers the possibility to disable the SWD port and can then release the associated pins for general-purpose I/O (GPIO) usage.
