MC9S08DV48ACLC - 8-bit S08 MCU 48KB Flash 40MHz CAN | NXP
MPN: MC9S08DV48ACLC ✗ Cuối đờiMC9S08DV48ACLC Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals on one die. The S08 family from NXP uses the HC08 instruction set enhanced with the BGND instruction, and the DV sub-family specifically targets automotive and industrial applications by adding an embedded CAN controller, embedded EEPROM, and on-chip emulation/debug. This places it in the broader taxonomy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The HCS08 core executes instructions in 1-3 bus cycles, yielding roughly twice the throughput of the legacy HC08 at the same bus frequency.
Key features include a 16-channel, 12-bit ADC with 2.5 us conversion time, 25 I/O pins, multiple timers (TPM, RTI, PIT), SCI/UART and SPI/I2C serial interfaces, and a built-in CAN 2.0 A/B controller. The part supports both 3.3V and 5V operation, has a wide operating temperature range suitable for industrial and automotive environments, and provides up to 32 interrupt/reset sources for responsive system behavior.
The MC9S08DV48ACLC uses a CISC (Complex Instruction Set Computing) architecture with variable-length instructions, allowing compact code density that maximizes the use of the 48KB Flash. Its Background Debug Mode (BGND) and on-chip debug logic enable non-intrusive in-circuit programming and debugging through a single-wire BDM interface, eliminating the need for an external emulator.
Typical applications include automotive body controllers, HVAC modules, industrial sensor interfaces, building automation, CAN nodes for distributed control, and low-cost motor control. The integrated CAN peripheral is the key differentiator versus non-CAN S08 parts, making this MCU well-suited for any 8-bit networked application.
When designing with this part, ensure the BDM pins are routed to a header for debug access during development. The internal voltage regulator allows single-supply operation but requires a decoupling capacitor on the VREG pin per the datasheet typical application circuit.
This page synthesizes distributor stock levels, drop-in compatible S08D alternatives, application guidance, and design notes beyond the manufacturer datasheet to support both new designs and field replacements.

Automotive CAN Body Controller
The MC9S08DV48ACLC is purpose-built for automotive body and chassis CAN nodes. Its integrated CAN 2.0 A/B controller handles 1 Mbit/s bus traffic without CPU intervention, while the 48 KB Flash accommodates CAN stack, diagnostics (UDS), and body-control application code. The 40 MHz CPU executes a typical CAN message handler in microseconds, leaving headroom for door/window/lamp logic.

Ghi chú thiết kế
Place a 100 nF decoupling capacitor as close as possible to each VDD/VSS pair, plus a bulk 4.7 uF capacitor on the main VDD rail. The internal voltage regulator requires a 100 nF decoupling cap on the VREG pin to ensure stable core logic supply. Estimated: at 40 MHz CPU, 5 V supply, and full peripheral activity the core draws approximately 25-30 mA, well within the regulator capability.
Route the BKGD and RESET lines with short traces to a debug header for programming access. Place the external crystal (or resonator) within 5 mm of the XTAL/EXTAL pins with a ground plane guard ring. Keep the CAN bus traces (PTA2/PTA3) away from switching signals and consider a 120-ohm termination resistor near the transceiver. Maintain a contiguous ground plane under the LQFP package to reduce EMI.
Do not leave the BKGD pin floating during normal operation - it must be pulled high through a 10 kohm resistor or driven by the BDM tool. The CAN TX/RX pins (PTA2/PTA3) require configuration of the CAN control registers before use; simply toggling the GPIO does not transmit CAN frames. Always configure the SOPT register to disable the RESET pin function if you need PTA5 as a general-purpose I/O.
The 12-bit ADC achieves its 2.5 us conversion spec only with the recommended input impedance below 10 kohm. Add an op-amp buffer or use RC filtering carefully when sampling high-impedance sensors. Estimated: a 1 kohm source impedance combined with the ADC sample capacitor yields a settling error below 0.5 LSB; higher impedances cause gain and linearity errors.
