To our customers, Old Company Name in Catalogs and Other Documents On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology Corporation, and Renesas Electronics Corporation took over all the business of both companies. Therefore, although the old company name remains in this document, it is a valid Renesas Electronics document. We appreciate your understanding. Renesas Electronics website: http://www.renesas.

1. Things to Check When Unpacking The M38K29T-ADF package consists of the following products. When unpacking it, check to see that all of these components are included. Table 1.
4. Setup This chapter describes how to set up the M38K29T-ADF. CAUTION Note on Setup: • Always shut OFF power before connecting this product. Otherwise, internal circuits may be damaged. (1) Mount the emulator MCU on the M38K29T-ADF. After checking the position of the No. 1 pin of the emulator MCU, mount the emulator MCU referencing Figure 4.1. (2) Insert the connector on the tip of the emulation pod probe to the socket on the emulator MCU. Universal part Position of No. 1 pin Figure 4.
(3) Connect the RESET cable (white) and the GND cable (black) of the emulation pod to pin RESET (TP3) and pin Vss (TP2) of the M38K29T-ADF respectively. Leave the Vcc cable (yellow) unconnected. (4) Set the MCU type select switch of the M38000TL2-FPD to the RSS/RFS side. (5) Connect an external power supply to pin Vcc (TP1) of the M38K29T-ADF. And connect the GND output of the power supply to pin Vss (TP2). Use a power supply whose rising time is 10 ms or less. Table 4.
(6) Set switches SW1 to SW3 according to your application. Table 4.2 describes the functions of the switches. Table 4.2 Functions of switches SW1, SW2 and SW3 of the M38K29T-ADF No. Name Function Factory-setting SW1 VREF Allows you to choose whether to apply Vcc or an external power supply to the MCU's pin VREF (43pin). For the M38K09RFS and M38K29RFS, set this switch to the Vcc side. Vcc SW2 USBVREF Allows you to choose whether to apply an external power supply to the MCU's pin USBVREF (64-pin).
5. Oscillator Circuit The M38K29T-ADF has a 6.0MHz oscillator on-board. Figure 5.1 shows a circuit diagram of the oscillator. When replacing the oscillator, the constants depend on an oscillator you use. It is advisable to refer to the values recommended by the manufacturers. Figure 5.
6. Reset Circuit Figure 6.1 shows the reset circuit and its waveform. In this product, reset is cleared in about 100 ms from the instant Vcc passes about 2.1 V after having started from 0 V. When Vcc drops down to about 2.1 V, reset turns effective. Detected power voltage (V) About 1.25 x (R1 + R2) / R2 Input voltage (IC3-2 pin) Output state (IC3-5 pin) Figure 6.1 Reset circuit and its waveform By using switch SW4, you can rest the MCU manually. Table 6.1 Function of switch SW4 (reset switch) No.
7. USB Port Circuit The M38K29T-ADF has some patterns for simplified evaluation of USB-related functions. Figure 7.1 shows a USB port circuit diagram. This diagram is a summarized version for reference purposes. Therefore, to design your circuit, see USB specifications or reference materials about 38K0 and 38K2 Group circuits. When the M38K29T-ADF is shipped from the factory, USB-related parts are not mounted. Mount them as necessary.
