Main Board
It provides major emulator functions including:
- Communication to a host PC;
- Non-intrusive control of the emulating module (pod);
- Breakpoint processing;
- Dual-port memory operations;
- Memory shadowing and on-the-fly access to the ICE resources;
- Trace recording;
- Clock setting;
- Time measurement.
The PICE main board uses the Altera® re-programmable ACEX PLD, which makes it possible to fit the functions of hundreds of glue logic chips into a one-square-inch piece of silicon. This approach improves reliability and dramatically reduces the emulator size without compromising features and performance. A few glue logic chips, memory chips, and a master microcontroller that handles communications to a host PC and reprogramming the ACEX unit, represent other components set on the Main board.
The main board abbreviation includes (from left to right): a) the part identifier "MR", b) the RoHS identifier ( "1" for leaded parts and "2" for lead-free), c) the target MCU family code (-52), d) the suffix that defines the on-ice memory size ('03' for 64K code + 64K data; '05' for 1M + 448K and '06' for 2M + 448K), and e) the suffix showing the the type of the link to a PC - 'U' for USB and 'R' - for RS-232C. For example: MR2-52-03U - provides emulation for 64K code + 64K data memory, does not support memory banking; MR2-52-05U - provides emulation for 1M code + 448K data memory, supports memory banking. Most of the PICE main boards can be used with either pod, however some pods can be used with certain main board with extended memory.
The Main board has three connectors on the top. One, a mini-USB connector, marked "LNK" is intended for connecting a link cable going to a PC USB or serial port. The second one, marked as "TRACER" in intended for connecting a flat trace cable TC-R1 with micro hooks at the ends of the cable wires. The cable allows entering up to 8 external signals and outputting up to four triggers to synchronize an oscilloscope, logic analyzer or other lab equipment. The third coaxial socket is intended for applying power to the ICE unit (3.3V, regulated, center positive).
The Main board has two connectors on the bottom to stack it with one of the pods with an execution (emulating) processor.
POD or Daughter Module
This module emulates a behavior of the target microcontroller under control of the PICE main board.
This module is built around an execution processor that emulates a behavior of the target MCU being under control of the loaded application program. PICE-52 can be equipped with a variety of changeable pods based either on special bonded-out devices (offen mentioned as "bondouts") or on standard microcontrollers working in the "Enhanced Hook" mode. The PICE main board controls a behavior of the emulating MCUs, i.e. it can stop and start real-time running and has an access to such device's resources as internal RAM, registers, etc. on-the-fly or when the program execution is halted.
Besides the execution processor, a few logic chips and passive components, each pod has a pair of connectors on the top to stack it to the Main board and another pair of connectors on the bottom to connect a mechanical package adapter.
The pod abbreviation includes (from left to right) the part identifier "PR", the RoHS identifier ( "1" for leaded parts and "2" for lead-free), the target MCU family code (-52) following a dash sign, the target group (ARX, ACC01, PLP, W77, etc.) sometimes following a slash sigh and a code of the execution MCU set on the POD (RD2, 769, etc.). For example, PR1-52-ARX/ID2 means the pod supporting a variety of the Atmel and Philips microcontrollers with 12- and 6-clock modes by means of the Atmel AT89C51ID2 microcontroller with the "Enhanced Hook" mechanism inside.
In order to find all PRx-52- pods available for the emulator scroll the window up and click on the "MCU Supported" button. Select the target MCU type and locate the pod you need. Or click the "Parts Selector & Prices" button to search our data base and get a quote on-line.
Adapter
This part provides mechanical connection of the emulator pod to the target board.
Depending on the type of the target microcontroller's mechanical package a PICE adapter is implemented either as a single transition board (for adaptation to the DIP and PLCC sockets) or as a set of a transition board and a special footer soldering onto the target board instead of the MCU chip (QFP, SOUC, SSOP, TSSOP and other fine pitch packages).
The Adapter abbreviation includes (from left to right) the part identifier "AR", the RoHS identifier ( "1" for leaded parts and "2" for lead-free), the target MCU family code (-52), the chip package type (for example "D" means DIP, "L" means PLCC, Q neans QFP, etc.), and the number of the chip pins (20, 40, 44, 68, etc.). For example, the AR2-52-L44 adapter supports all 8051 microcontrollers in 44-pin PLCC packages and can be used with any PICE-52 pod; the AR1-52-PLP1-S20 adapter can be used only with a PR1-52-PLP1/93x pod for NXP microcontrollers in a SOIC 20-pin package.
In order to find all the adapters available for the emulator scroll the window up and click on the "MCU Supported" button. Select the target MCU type to see all the adapters available for the target MCU. Or click the "Parts Selector & Prices" button to search our data base and get a quote on-line.
