ST SPC58 B Line Emulation Adapter System

Transcription

1 _ V1.1 Hardware Reference ST SPC58 B Line Emulation Adapter ST SPC58 B Line Emulation Adapter System ST SPC58 B line emulation adapter primary use case is providing Nexus trace functionality for the SPC58 B line devices in the QFP64 and the QFP100 packages, where Nexus trace port is not available. The emulation adapter is based on the 144-pin superset device and provides the adaptation to 64-pin and 100-pin QFP target package. Alternative use case is also a standalone operation. In this case customer can start developing and testing the application while his target may not be available yet. ST SPC58 B line emulation adapter is based on the SPC582B60E5 device in the QFP 144 package, only in which the Nexus trace port is exposed and available. It s a superset device with 1MB program flash and can emulate all ST SPC58 B line devices in smaller packages. Complete emulation adapter is split into individual parts which makes it flexible when support for different target packages is required. A typical setup in conjunction with the target contains: IEA-SPC582B (Microcontroller part) Pin Count Conversion Board Solder Part isystem, July /12

2 Optional is a power supply part, which is used for emulation adapter standalone operation without the target or when there are problems with the target supplying the power. Minimally the IEA-SPC582B (Emulation Adapter) and the IEA-PS (Power Supply) items are required for standalone operation without the target. Minimal setup for standalone operation Ordering Code: IEA-SPC582B IEA-PS QFP100 IEA-SPC582B-TQ100 IA100TQ-SOLDER QFP64 IEA-SPC582B-ATQ64 IA64ATQ-SOLDER Description: Emulation Adapter Emulation Adapter Power Supply (optional) 100-Pin Count Conversion Board Solder Part TQ100QFP (14x14) 64-Pin Count Conversion Board Solder Part TQ64QFP (10x10) The emulation adapter can be used in conjunction with isystem ic5000, ic5500 and ic6000 debug and test tool or any other third party tool supporting ST SPC58 B line Nexus trace port. Debug tool connects to the standard 38-pin Mictor connector (P6) providing debug and Nexus trace interface connection. isystem, July /12

3 Jumper configuration J1: target reset configuration Jumper J1 connects the reset line between the emulation device and the target. By default J1 is populated. J2 and J3: clock source configuration Jumpers J2 and J3 select clock source for the emulation device. Per default, both jumpers are set to position 1-2, which yields the clock source being used from the target. Note that the emulation adapter may not operate when crystal circuit is used in the target. Typical design guideline is that the crystal should be as close as possible to the microcontroller. However, it may happen that the target crystal may not oscillate in conjunction with the emulation adapter since clock lines (XTAL, EXTAL) between the target and the emulation device on the emulation adapter can become too long consequentially too much affecting the impedance of the crystal circuit. There should be no problem if the oscillator is used in the target. If an oscillator in the target is not an option and the target crystal doesn t oscillate in conjunction with the emulation adapter, clock from the emulation adapter must be used (J2 & J3 position 2-3). In this case, a crystal circuit must be assembled on the emulation adapter. Crystal circuit Note: Crystal circuit is located in the corner of the emulation adapter, next to the 38-pin Mictor connector P6. Per default 10pF capacitors are populated for C1 and C2 and the crystal Q1 is not populated. Note that C1 and C2 values are valid for 40MHz crystal only. If different crystal is used, the default 10 pf capacitors must be replaced with proper value. isystem, July /12

4 J4 & J6: GND connecting points Real target microcontroller in the QFP package provides an exposed GND pad in the middle of the microcontroller at the bottom side of the package. This provides GND connection between the microcontroller and the target. In case of the emulation adapter usage, the solder part (IA100TQ- SOLDER or IA64ATQ-SOLDER) is soldered instead of the microcontroller. Note that the available solder parts at the introduction of this emulation adapter, did not provide support for the exposed GND pad. For this reason, user must ensure replacement GND connection between the emulation adapter and the target using a dedicated GND wire. Without this connection, the system will not work. Use provided GND wire which comes along the emulation adapter and plug it to the pin J6 (see picture above) on the emulation adapter. Connect the other side to the ground potential on the target - as close as possible to the microcontroller respectively solder part being soldered instead of the microcontroller. This connection must be quality and reliable otherwise debugging and tracing over the Nexus trace port may not work. Alternatively, GND connection can be also established over the J4 ground bridge. P5: power selection The P5 header row is used for power supply selection. Refer to the microcontroller user manual for more details which power supply designation belongs to which power supply.

If a different power source is to be used (e.g. in case of standalone operation), jumpers must be removed, and power source must be applied to CVDD_HV_OSC (pin 4), CVDD_HV_ADV (pin 6), CVDD_HV_ADR_S (pin 8), CVDD_HV_IO_MAIN (pin 10), CVDD_HV_FLA (pin 12) and GND (pins 22, 24, 26) signals. isystem, July /12

5 Optional emulation adapter power supply (ordering code: IEA-PS), which can provide 3.3V or 5V voltage, connects on top of the emulation adapter directly to the P5 header row and allows standalone usage of the emulation adapter. This is convenient when the target is not available or it s not adjusted for the emulation adapter connection yet.
