1. Things to Check When Unpacking The M38C89T-ADF package consists of the following products. When unpacking your package, check to see that all of these components are included. Table 1.1 Contents of the M38C89T-ADF package Item Quantity M38C89T-ADF temporary target board 1 M38C89T-ADF User's Manual (this manual) 1 * If you find any item missing or faulty, or any suggestion, contact your local distributor. 2.
3. Specifications Table 3.1 lists specifications of the M38C89T-ADF. Table 3.1 Specifications of the M38C89T-ADF Applicable MCUs IC1: 38C8 Group (M38C89MF-xxxFP/M38C89EFFP) IC2: M38C89RLFS (Emulator MCU) Clock Main clock: 4.0MHz oscillator mounted (for IC2 only) (RC oscillation: approx. 2 MHz*1) Sub clock: 32.
4. Setting Up This chapter describes how to set up the M38C89T-ADF. With this product, the debugging with an emulator MCU and M38C89MF-xxxFP/M38C89EFFP is possible. Use the M38C89T-ADF mounting one of these MCUs. To use an emulator MCU: Read "4.1 Connecting to the Emulator" (this page) To use the M38C89MF-xxxFP/M38C89EFFP: Read "4.2 Mounting the M38C89MF-xxxFP/M38C89EFFP" (page 8) CAUTION Note on Setting Up: • Always shut OFF power before connecting the M38C89T-ADF.
(4) Connecting the control signal lines Connect the three lines of the emulation pod to the test pins. VCC cable (yellow) ........... VccM (test pin with a yellow bead) GND cable (black) ............. GND (test pin with a black bead) Reset cable (white) ............. RESET (test pin with a white bead) Figure 4.2 Connecting the M38C89T-ADF (5) Setting jumpers Set the jumpers (JP3 to JP7) according to your application. Table 4.1 describes the functions of the jumpers for the emulator MCU (IC2). Table 4.
4.2 Mounting the M38C89MF-xxxFP/M38C89EFFP (1) Mounting parts Mount the socket for IC1 and the oscillator circuit part. Table 4.2 lists the applicable parts for this board. Table 4.2 Socket for the M38C89MF-xxxFP/M38C89EFFP and applicable oscillator circuit No. Part No. Type name Remarks Manufacturer 1 IC1 IC51-1444-1354-18 Yamaichi Electronics Co., Ltd. 144-pin socket 2 X1 CST4.00MGW040 Murata Manufacturing Co., Ltd. Built-in capacitor type, 4 MHz 3 XC1 SP-T2B 32.
5. Oscillator Circuit 5.1 Main Clock Generator Circuit The main clock of 4.0 MHz is mounted (X2 only). Figure 5.1 shows the main clock generator circuit. Figure 5.1 Main clock generator circuit 5.2 Sub Clock Generator Circuit The sub clock generator circuit is shown in Figure 5.2. The sub clock oscillates at 32.768 kHz. Capacitors C19 and C20 have a capacitance of 10 pF, while resistor R11 has a resistance of 0 Ω and resistor R12 a resistance of 6.8 MΩ. Components are not mounted on the IC1 side.
5.3 How to Use the RC Oscillator Circuit The clock selection circuit is shown in Figure 5.3. Oscillation can be switched between RC oscillation and the oscillator by changing the jumpers. The following procedure explains how to switch to RC oscillation. (1) Cut jumper JP4. (When JP4 is cut, the OSCSEL pin becomes high.) (2) To enable RC oscillation in IC1, set resistor R1 (see Table 4.3) in jumpers JP1 and JP2 described in Figure 5.1. To enable RC oscillation in IC2, set resistor R10 (see Table 4.
8. Pin Layout Table 8.1 lists the pin layout of the connectors. Table 8.1 Pin layout of the M38C89T-ADF J2 Signal J3 Pin No. Signal Signal J4 Pin No. Signal Signal Signal Pin No.
