selection reference guide

The TMS370 8-Bit Microcontroller Product Selection Guide Configurations Table, commonly called the

Selection Reference Guide (see Table 4), provides the user with an easy-to-use guide that includes the

following specific device information by subfamilies: product family description (device type, part number,

package and temperature options, and pin count); memory [program memory (ROM, EPROM), data memory

(EEPROM, RAM) and any capability of off-chip memory expansion]; and peripherals (timers, serial interfaces,

A / D channels, I / O, clock generators, and OTP and reprogrammable devices). The following symbol footnotes

are used in Table 4:

† Packages: FN = PLCC, FZ = CLCC, N = PDIP, JD = CDIP, NJ = PSDIP (formerly N2), JC = CSDIP, NM = PSDIP, JN = CSDIP

‡ Temperatures: ROM device types have L = 0

°C to +70°C, A = – 40°C to +85°C, and T = – 40°C to +105°C temperature options; ROM-less, OTP

and UV-EPROM device types only have T.

§ PACT SCI: PACT includes a mini-SCI. SCI1 module has 3-pin configuration while SCI2 module has 2-pin configuration.

¶ RAM: Includes 256 bytes of standby RAM

# Memory: Includes secured memory feature

|| Max Freq: Supports maximum operating frequency of 3 MHz SYSCLK

kPACT WDOG: PACT includes a watchdog timer

hADC1 Channels: 8 channels A/D for 44 pin package, 4 channels A/D for 40 pin package

◊ Timers: Timer 1 (T1) includes a watchdog timer programmable as a general purpose 16-bit timer

Ψ44/40 Packages: 44 pins for FN, FZ packages. 40 pins for N, JD, NJ (formerly N2), JC packages.

Φ68/64 Packages: 68 pins for FN, FZ packages. 64 pins for NM, JN packages

¥ TMS370CxCx SCI: Operable in asynchronous mode only

∆ Converter Socket: Requires a TMDS37788OTP converter socket

♣Requires software modification (see the TMS370CxBx Data Sheet (literature number SPNS038))

Table 4 is a continuous table and only the applicable symbol footnotes are listed on each page.

development systems support tools

The TMS370 development system support tools listing shown in Table 5 identifies the available development

support tools (by tool description and part number) for each of the TMS370 subfamilies (’x0x, ’x1x, ’x2x, ’x32,

’x36,

…, ’xCx).
