Product Overview & Identity
The single-row table below summarizes the most relevant specifications. These values represent the typical and maximum figures derived from the official manufacturer datasheet to aid in discovery and technical clarity.
| Core | Max CPU | Flash | SRAM | Package | I/O | ADC | Timers | Comm | Vdd | Op Temp |
|---|---|---|---|---|---|---|---|---|---|---|
| Cortex-M23 | 72 MHz (max) | 64 KB | 8 KB | TSSOP-20 | ~20 | 12-bit ADC | 16-bit, PWM | UART, SPI, I2C | 1.8–3.6 V | -40°C to +85°C |
Core Performance, Clocking & Power
CPU & Architecture
The Arm Cortex-M23 core reaches a maximum clock of 72 MHz. It offers integer throughput of approximately 0.5–1.5 DMIPS/MHz, making it highly efficient for real-time control loops and lightweight signal processing tasks.
Power Consumption Analysis
Designed for battery-sensitive applications, the MCU exhibits low microamp standby currents. Use typical values for design and maximum values for worst-case power budgeting.
| Mode | Typical | Max |
| Active (72 MHz) | ~6–10 mA | ~12–15 mA |
| Sleep | ~50–200 µA | ~500 µA |
| Standby | <1–5 µA | ~10 µA |
Using a 3.3 V, 1000 mAh cell: With a 1% active duty cycle (10 mA) and 99% sleep cycle (200 µA), the average current is approximately 0.298 mA. This yields a theoretical lifespan of ~3,350 hours (~139 days). Engineers should account for regulator inefficiencies and peak current spikes during production planning.
Memory, Peripherals & I/O
Memory Map Allocation
The fixed 64 KB Flash and 8 KB SRAM require strategic partitioning for optimal performance.
- Bootloader: 8–16 KB recommended.
- Application: 40–48 KB available space.
- OTA Buffers: Stream telemetry to save RAM.
Peripheral Integrated Features
Despite its small TSSOP-20 footprint, the MCU is feature-dense:
Hardware Integration & Thermal Limits
PCB Layout Priorities
- ✔ Place 0.1 µF decoupling caps close to VDD.
- ✔ Keep oscillator traces as short as possible.
- ✔ Isolate analog ADC traces from digital noise.
Environmental & Reliability
The industrial operating range is -40°C to +85°C. Although the TSSOP-20 package lacks a dedicated thermal pad, it is recommended to use copper pours to dissipate heat if sustained high-frequency operation is required in enclosed environments.
