Product details
Overview
IA188EM-PQF100I-R-03 from Innovasic Semiconductor is a radiation-tolerant, 16-bit microcontroller derivative of the AMD Am188ES architecture, operating at up to 25 MHz with 1 MB addressable memory space, integrated DMA controller, dual 16-bit timers, and asynchronous/synchronous serial ports. It serves as a drop-in replacement for legacy Am188ES in avionics, industrial control, and space-grade embedded systems requiring long-term component availability and extended temperature operation.
For engineers reviewing the IA188EM-PQF100I-R-03 datasheet, IA188EM-PQF100I-R-03 pinout, IA188EM-PQF100I-R-03 application, or IA188EM-PQF100I-R-03 equivalent, key selection criteria include PQFP-100 package compatibility, -40°C to +85°C industrial temperature grade, synchronous bus timing with programmable wait states, and MILES™-enhanced reliability features for mission-critical firmware execution.
Technical Context
The IA188EM-PQF100I-R-03 implements a fully static, 16-bit CISC core with 25 MHz maximum clock frequency, 1 MB linear address space segmented into upper/midrange/lower memory regions, and hardware-assisted bus cycle control via s2_n–s0_n status signals and programmable chip selects (UMCS, MMCS, LMCS, PCS0–PCS6). Its bus interface supports both synchronous and asynchronous ready signaling (srdy/pio6 and ardy), enabling flexible interfacing with SRAM, PSRAM, and peripheral ASICs.
It integrates two independent 16-bit programmable timers (T0/T1) with compare/capture capability, a third 16-bit timer (T2) for watchdog or event counting, an 8-channel DMA controller with priority arbitration, and dual serial interfaces: one asynchronous UART (TXD/RXD) and one synchronous SPI-compatible port (SCLK/SDATA/SRDY) with configurable baud rate generation and frame control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit CISC, fully static, Am188ES-compatible instruction set with MILES™ enhancements for radiation tolerance. |
| Max Clock Frequency | 25 MHz - enables deterministic real-time response in safety-critical control loops without dynamic timing margining. |
| Address Space | 1 MB linear - supports direct access to external memory-mapped peripherals and large code/data segments without bank switching. |
| Memory Interface | Synchronous bus with programmable wait states, 10 chip select outputs (UMCS/LMCS/MMCS/PCS0–PCS6), and refresh control for DRAM. |
| Timers | Three 16-bit timers: T0/T1 support input capture/output compare; T2 operates as watchdog or event counter with interrupt capability. |
| DMA Channels | 8-channel controller with priority arbitration, channel-specific control registers, and burst/single transfer modes for offloading CPU data movement. |
| Serial Interfaces | One asynchronous UART (TXD/RXD) and one synchronous serial port (SCLK/SDATA/SRDY) supporting master/slave SPI-like communication. |
Pinout & Package
IA188EM-PQF100I-R-03 is housed in a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm pitch, JEDEC MS-026 compliant footprint, and industrial-grade thermal characteristics (θJA = 45°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A16–A0 | Address Bus | 21-bit synchronous tristate outputs for full 1 MB addressing; A16–A0 used directly for memory and I/O decode. |
| AO15–AO8 | Address-Only Bus | 8-bit synchronous tristate outputs unique to IA188EM; separates address from data to eliminate bus contention in multiplexed designs. |
| AD7–AD0 | Address/Data Bus | 8-bit bidirectional synchronous tristate bus shared between low-order address and data; requires external latch on ALE. |
| WR_N, RD_N | Write/Read Strobes | Active-low synchronous control signals with tristate capability; define valid data window timing for external memory cycles. |
| PCS0–PCS6 | Peripheral Chip Selects | 7 dedicated synchronous outputs for selecting discrete peripherals or FPGA logic blocks; each independently programmable in memory map. |
| PIO0–PIO31 | Programmable I/O Pins | 32 open-drain asynchronous I/O pins with direction and mode registers; usable as GPIO, interrupt inputs, or timer inputs/outputs. |
| INT0–INT4 | Maskable Interrupt Inputs | Five asynchronous level-sensitive interrupt request lines; support nested priority handling via IMASK and INTSTS registers. |
| RES_N | Reset Input | Active-low asynchronous reset with internal pull-up; initiates hardware reset sequence including register initialization and vector fetch from FFFF0h. |
Key Features
| Feature | Design Value |
|---|---|
| MILES™ Radiation Hardening | Enhanced latch-up immunity and single-event effect mitigation validated per MIL-STD-883H Method 1019.8 for space applications. |
| Programmable Wait States | Configurable 0–15 wait states per chip select region enable reliable interfacing with slow SRAM, flash, or custom logic without glue logic. |
| Dual Serial Ports | Independent UART and synchronous serial interface allow simultaneous host communication and sensor/actuator control over separate physical layers. |
| Hardware DMA Engine | 8-channel controller with dedicated registers per channel reduces CPU overhead during high-bandwidth data transfers (e.g., ADC streaming or display updates). |
| Flexible Timer System | T0/T1 support input capture, output compare, and PWM generation; T2 provides watchdog reset or precise event timing with interrupt on overflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Am188ES-25KC | Original AMD part; lacks MILES™ radiation hardening and has discontinued lifecycle status. | Not suitable for new designs requiring long-term supply or radiation tolerance. | Select IA188EM-PQF100I-R-03 when radiation resilience, extended product lifetime, or industrial temperature range is required. |
| IA186EM-PQF100I-R-03 | 8-bit data bus variant (AD15–AD8 present); reduced memory bandwidth vs. IA188EM's AO15–AO8 + AD7–AD0 split bus. | Better suited for cost-sensitive 8-bit peripheral control where full 16-bit throughput is unnecessary. | Choose IA188EM-PQF100I-R-03 when higher memory bandwidth, larger address space, or AO/AD separation improves system timing margin. |

Does the IA188EM-PQF100I-R-03 support external memory expansion?
Yes, the IA188EM-PQF100I-R-03 supports external memory expansion through its 21-bit address bus (A16–A0), 8-bit multiplexed address/data bus (AD7–AD0), and dedicated address-only bus (AO15–AO8). It provides 10 programmable chip select outputs (UMCS, LMCS, MMCS, PCS0–PCS6) with individually configurable timing, enabling direct connection to SRAM, PSRAM, flash, and peripheral ASICs without external glue logic.
How does the IA188EM-PQF100I-R-03 differ from the original AMD Am188ES?
The IA188EM-PQF100I-R-03 is a drop-in compatible enhancement of the AMD Am188ES, featuring MILES™ radiation hardening, extended industrial temperature rating (-40°C to +85°C), improved ESD robustness, and continued long-term availability. Electrical and timing specifications match the Am188ES-25KC, ensuring full firmware and hardware compatibility while adding reliability features essential for aerospace and critical infrastructure use.
What serial communication interfaces are integrated into the IA188EM-PQF100I-R-03?
The IA188EM-PQF100I-R-03 integrates two independent serial interfaces: one asynchronous UART (TXD/RXD pins) supporting standard RS-232/RS-485 levels with external transceivers, and one synchronous serial port (SCLK/SDATA/SRDY) configurable as SPI master or slave. Both interfaces have dedicated control registers (SPBAUD, SPCT, SPSTS) and support programmable baud rates, frame formats, and interrupt-driven operation.
Is the IA188EM-PQF100I-R-03 pin-compatible with other packages in the IA188EM family?
Yes, the IA188EM-PQF100I-R-03 shares identical pinout and signal definitions with the IA188EM-TQF100I-R-03 (TQFP-100) variant. Both use the same 100-pin grid, matching pin functions for all address, data, control, and I/O signals. This allows direct PCB-level substitution between PQFP and TQFP packages without layout changes or firmware modification.
