Product details
Overview
STM32F100ZDT6B from STMicroelectronics is a high-density value-line Arm® Cortex®-M3 MCU with 384 KB Flash, 32 KB SRAM, 24 MHz max CPU frequency, dual 12-bit DACs, and 112 I/O pins in LQFP144 package-used in industrial HMI controllers requiring integrated analog output and LCD interface support.
For engineers reviewing the STM32F100ZDT6B datasheet, STM32F100ZDT6B pinout, STM32F100ZDT6B application, or STM32F100ZDT6B equivalent, key selection criteria include Flash/SRAM size, DAC count and resolution, timer advanced-control capability (dead-time generation), and LCD parallel interface (8080/6800 modes) for embedded display systems.
Technical Context
The device integrates an Arm Cortex-M3 core with single-cycle multiply/hardware divide, supporting deterministic real-time control. Its clock system includes dual oscillators (4–24 MHz HSE + 32 kHz LSE), programmable PLL, and factory-trimmed 8 MHz HSI for boot and low-power operation.
Memory architecture features flexible static memory controller (FSMC) with four chip selects for NOR/PSRAM/SRAM expansion, plus dedicated LCD parallel interface supporting 8080/6800 bus protocols-enabling direct connection to segment or graphic LCD panels without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3, 24 MHz max - enables deterministic interrupt latency & real-time task scheduling in resource-constrained industrial firmware. |
| Flash Memory | 384 KB - sufficient for complex control algorithms with bootloader, OTA update partition, and safety-critical redundancy. |
| SRAM | 32 KB - supports multi-threaded RTOS operation with stack/heap allocation for communication stacks (e.g., Modbus TCP). |
| Analog Peripherals | 1 × 12-bit ADC (16 ch, 1.2 µs), 2 × 12-bit DACs - enables closed-loop analog feedback (e.g., motor current sensing + voltage reference generation). |
| Timers | 7 × 16-bit general-purpose, 1 × advanced-control (6-channel PWM + dead-time), 2 × watchdog - meets IEC 61800-5-2 functional safety timing requirements. |
| Communication Interfaces | 3 × USART (LIN/IrDA), 2 × I²C (SMBus), 3 × SPI (12 Mbit/s), CEC - supports multi-protocol fieldbus gateways and consumer appliance control. |
| I/O Pins | 112 GPIO, 5 V-tolerant on most - allows direct interfacing with legacy 5 V sensors, encoders, and industrial logic without level shifters. |
| Package | LQFP144 (20 × 20 mm) - provides thermal margin for continuous operation at 85°C ambient in enclosed control cabinets. |
Pinout & Package
LQFP144 package, 20 × 20 mm body, 0.5 mm pitch, exposed pad for thermal dissipation. Pinout validated per STMicroelectronics DS5944 Rev 11 Figure 3 and Table 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply / Ground | Dual 3.3 V domains: VDDA (analog) and VDD (digital) require separate filtering to maintain ADC/DAC SNR > 70 dB. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O | All 112 pins support remappable alternate functions (USARTx_TX, TIMx_CHy, I²Cx_SCL) - simplifies PCB layout reuse across variants. |
| PC13–PC15 | RTC oscillator inputs | Support 32.768 kHz crystal with built-in load capacitance tuning - eliminates external caps for battery-backed real-time clock. |
| PD0–PD15, PE0–PE15 | LCD data/address bus | Direct 8080/6800 mode interface to monochrome/graphic LCDs - reduces BOM by removing display controller IC. |
| NRST | Reset input | Active-low, Schmitt-triggered, with internal pull-up - compatible with open-drain supervisor ICs (e.g., TPS3808). |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Static Memory Controller (FSMC) | 4 chip-select outputs with configurable timing for NOR/PSRAM/SRAM - enables local code execution from external memory, extending effective Flash capacity. |
| Advanced-Control Timer (TIM1) | 6-channel complementary PWM with programmable dead-time (1–1023 ns) and emergency stop - meets IEC 61800-5-2 Class 2 safe torque off (STO) requirements. |
| Temperature Sensor | Integrated calibrated sensor (±1.5°C accuracy) referenced to VDDA - enables thermal derating of motor drives without external thermistors. |
| Serial Wire Debug (SWD) | 2-pin debug interface (SWCLK/SWDIO) with SWO trace - supports real-time variable monitoring and non-intrusive profiling in production firmware. |
| CRC Calculation Unit | Hardware CRC-32 generator - accelerates firmware image integrity checks during boot and OTA updates, reducing CPU overhead by >95% vs software CRC. |

FAQ
What is the maximum operating temperature for STM32F100ZDT6B?
The STM32F100ZDT6B is rated for industrial temperature range: –40°C to +85°C ambient. Thermal performance is validated per ST's DS5944 Rev 11 Section 6.4, with θJA = 27.5°C/W in LQFP144 package. Derating above 70°C ambient requires PCB copper pour under the exposed pad and airflow ≥0.5 m/s.
Does STM32F100ZDT6B support USB connectivity?
No, the STM32F100ZDT6B does not include a USB peripheral. It provides up to three USARTs (with IrDA/LIN), two I²C, three SPI, and CEC interfaces-but no USB device or host controller. For USB-enabled designs, consider STM32F103 or STM32F072 series.
Can the internal 8 MHz RC oscillator be used as the system clock source?
Yes-the factory-trimmed 8 MHz HSI oscillator can serve as the main system clock via the RCC configuration. It achieves ±1% accuracy over temperature and voltage, sufficient for UART communication at 115.2 kbps without external crystal. Calibration register access allows runtime fine-tuning.
How many independent PWM channels does STM32F100ZDT6B support?
The device supports up to 24 independent PWM outputs: seven 16-bit timers provide up to four channels each (28 total), but channel overlap occurs due to shared resources. The advanced-control timer (TIM1) delivers six complementary PWM channels with dead-time insertion, while general-purpose timers offer additional non-complementary outputs.
