SN8P2740 Series
ADC, OP-amp, Comparator 8-Bit Micro-Controller
17DEVELOPMENT TOOL
SONIX provides ICE (in circuit emulation), IDE (Integrated Development Environment) and EV-kit for SN8P2740
development. ICE and EV-kit are external hardware devices, and IDE is a friendly user interface for firmware
development and emulation. These development tools‟ version is as following.
ICE: SN8ICE2K Plus II. (Please install 16MHz crystal in ICE to implement IHRC emulation.)
ICE emulation speed maximum: 8 MIPS @ 5V (e.g. 16Mhz crystal, Fcpu = Fosc/2).
EV-kit: EV2740 KIT REV: V1.0.
IDE: SONiX IDE M2IDE_V129 and later version.
Writer: MPIII writer.
Writer transition board: SN8P2742 / SN8P2743
17.1 SN8P2740 EV-KIT
SONIX provides SN8P2740 series MCU which includes PWM, ADC, Comparator and OP analog functions. These
functions aren‟t built in SN8ICE2K Plus 2. To emulate the functions must be through SN8P2743 real chip. The real chip
provides an EV-KIT to achieve PWM and the analog functions emulations. For SN8P2743/42 ICE emulation, the EV-Kit
includes OP/Comparator/PWM/ADC/LVD2.4V/3.6V and switch circuits.
EV2740 KIT PCB Outline:
CON1: Connect to SN8ICE2K Plus 2 JP3 (EV-KIT communication bus with ICE, control signal, and the others).
CON2: Connect to SN8ICE2K Plus 2 CON1 (includes GPIO, EV-KIT control signal, and the others).
S1: LVD24V/LVD36V control switch. To emulate LVD2.4V flag/reset function and LVD3.6V/flag function
Switch No.

LVD 2.4V Inactive
LVD 3.6V Inactive
LVD 2.4V Active
LVD 3.6V Active
S2: SN8P2743 EV-chip reset key. If EV-KIT active fail, press S2 to reset EV-KIT Real Chip (U1).
JP23: GPIO connector.
JP18: Using ADC function before, SN8ICE2K Plus 2 AVREFH/VDD jumper pin must be removed. If ADC external
reference voltage function enable, JP18 (AVREFH) or P40O pin is external reference voltage input.
JP17: Observe CMP0 input/output voltage.
JP16: Observe CMP1 input/output voltage.
JP8: Observe CMP2 input/output voltage.
JP7: Observe OP-Amp input/output voltage (OP3P = OPP, OP3N = OPN, OP3O = OPO).
U1: SN8P2743 EV-chip for analog functions emulation.
